A large squad of police officers arrived, along with reporters, turning the situation into a full-blown chaotic event. They noisily searched the house, slamming doors and questioning the family, but found no one. The confusion peaked when the grandfather, who was in the attic and thought the police were deserters from General Meade's army, attacked them, even shooting an officer.

Nothing ever satisfies them, as they always believe something is wrong.

40. Write a letter to the editor of a leading newspaper suggesting measures to upgrade the standard about the bad influence of TV channels.

From,
R. Kumar,
15, Park Street,
Chennai - 600 028.

20th September 2025

To,
The Editor,
The Hindu,
Chennai - 600 002.

Sir/Madam,

Subject: Concern over the declining standards and negative influence of TV channels - Reg.

Through the columns of your esteemed newspaper, I wish to express my deep concern over the deteriorating quality of programmes broadcasted on various television channels today. Television has a massive reach and a profound impact on society, especially on the impressionable minds of children and youth. Unfortunately, many channels are prioritizing TRP ratings over social responsibility.

Many TV shows are filled with excessive violence, vulgarity, and unrealistic portrayals of life, which can negatively influence viewers. The so-called 'reality shows' often promote conflict and sensationalism instead of talent. This constant exposure to negative content is detrimental to the moral and social fabric of our society. There is a noticeable lack of educational, informative, and value-based programming during prime time.

I suggest the following measures to address this issue: The broadcasting authorities must enforce stricter content regulation and censorship. Channels should be mandated to allocate prime-time slots for programmes that promote education, cultural values, and scientific temperament. Furthermore, a robust and clear content rating system should be implemented. I urge the concerned authorities and content creators to take immediate steps to elevate the standard of television programming for the betterment of society.

Thank you.

Yours truly,
R. Kumar

II. Answer any 7 questions:- (Q.No.22 is compulsory) (7×2=14)

13) State Newton's second law.

Solution: Newton's second law of motion states that the force acting on a body is directly proportional to the rate of change of its linear momentum and the change in momentum takes place in the direction of the force. Mathematically, F ∝ (mv - mu)/t, which leads to F = ma.

14) Distinguish between ideal gas and real gas.

Solution:
  • Ideal Gas: The volume occupied by the molecules is negligible compared to the volume of the container. The force of attraction between the molecules is zero. It obeys the ideal gas equation (PV=nRT) at all temperatures and pressures.
  • Real Gas: The volume occupied by the molecules is not negligible. There are intermolecular forces of attraction. It obeys the ideal gas equation only at high temperatures and low pressures.

15) What is rust? Give the equation for formation of rust?

Solution: Rust is a reddish-brown hydrated ferric oxide (Fe₂O₃·xH₂O) formed when iron or its alloys are exposed to oxygen and moisture for a prolonged period.
Equation for formation of rust:
4Fe + 3O₂ + xH₂O → 2Fe₂O₃·xH₂O (Rust)

16) Classify the following substance into deliquescent and hygroscopic. Con sulphuric acid, Copper sulphate penta hydrate, Silica gel, Calcium chloride and Gypsum salt.

Solution:
  • Deliquescent Substance: Calcium chloride (absorbs moisture and dissolves in it).
  • Hygroscopic Substances: Concentrated sulphuric acid, Copper sulphate pentahydrate, Silica gel, Gypsum salt (absorb moisture from the air without dissolving).

17) Write the reaction for photosynthesis?

Solution: The balanced chemical equation for photosynthesis is:
6CO₂ (Carbon dioxide) + 6H₂O (Water) --(Sunlight / Chlorophyll)--> C₆H₁₂O₆ (Glucose) + 6O₂ (Oxygen)

18) a) Give the common name of the Hirudinaria granulosa. b) What does CNS stands for?

Solution:
a) The common name of Hirudinaria granulosa is the Indian Cattle Leech.
b) CNS stands for Central Nervous System.

19) Draw and label the diagram.

Solution: The diagram shows the structure of a stomata. The key parts to be labelled are: Diagram of a Stomata with labels
  • Stomatal Pore (Stoma): The opening through which gas exchange occurs.
  • Guard Cells: A pair of bean-shaped cells surrounding the stomatal pore, which control its opening and closing.
  • Chloroplasts: Organelles within the guard cells that perform photosynthesis.
  • Nucleus: Present in each guard cell.
  • Epidermal Cells: The surrounding cells of the leaf's surface.

20) What is bolting? How can it be induced artificially?

Solution: Bolting is the premature flowering of a plant, accompanied by the rapid elongation of the internodes of the stem, just before flowering. This phenomenon is commonly seen in rosette plants like cabbage and beetroot.
Artificial Induction: Bolting can be induced artificially by the application of gibberellins.

21) What do you understand by the term phenotype and genotype?

Solution:
  • Phenotype: It refers to the observable physical or biochemical characteristics of an organism, such as height, eye color, or blood type. It is determined by both genetic makeup and environmental factors.
  • Genotype: It refers to the complete genetic makeup of an organism, i.e., the specific combination of alleles for a particular gene.

22) (Compulsory) The work done in moving a charge of 10C across two points in a circuit is 100J. What is the potential difference between the points.

Solution: Given:
  • Work done (W) = 100 J
  • Charge (Q) = 10 C
The formula for potential difference (V) is: V = W / Q
V = 100 J / 10 C
V = 10 Volts
Therefore, the potential difference between the points is 10 V.

Part - III

III. Answer any 7 questions:- (Q.No.32 is compulsory) (7×4=28)

23) Define inertia. Give its classification.

Solution: Inertia: It is the inherent property of a body to resist any change in its state of rest or state of uniform motion, unless it is acted upon by an external unbalanced force.
Classification of Inertia: Inertia is classified into three types:
  1. Inertia of Rest: The inability of a body to change its state of rest by itself. (e.g., When a bus starts suddenly, passengers tend to lean backwards).
  2. Inertia of Motion: The inability of a body to change its state of uniform motion by itself. (e.g., An athlete runs a certain distance before a long jump to gain momentum).
  3. Inertia of Direction: The inability of a body to change its direction of motion by itself. (e.g., When a fast-moving bus takes a sharp turn, passengers are thrown sideways).

24) a) List any 2 properties of light. b) Why does the sky appear in blue colour?

Solution:
a) Two properties of light:
  1. Rectilinear Propagation of Light: Light travels in a straight line in a homogenous medium.
  2. Reflection of Light: The bouncing back of light rays when they fall on the surface of an object.
b) Why the sky appears blue: The sky appears blue due to a phenomenon called Rayleigh scattering. When sunlight enters the Earth's atmosphere, the gases and particles in the air scatter the light. Blue light is scattered more than other colors because it travels as shorter, smaller waves. This scattering causes the blue light to be dispersed all over the sky, making it appear blue to our eyes.

25) Match the items in column I to the items II

Solution:
  • i) electric current - ampere
  • ii) potential difference - volt
  • iii) specific resistance - ohm meter
  • iv) electric power - watt

26) a) What happens when MgSO₄·7H₂O is headed: Write the appropriate equation. b) Define Solubility.

Solution:
a) Heating MgSO₄·7H₂O (Epsom Salt): When Magnesium sulphate heptahydrate (MgSO₄·7H₂O) is gently heated, it loses its seven water molecules of crystallization and becomes anhydrous magnesium sulphate (MgSO₄), which is a white crystalline solid.
Equation: MgSO₄·7H₂O(s) --(Heat)--> MgSO₄(s) + 7H₂O(g)
b) Solubility: Solubility is defined as the maximum amount of a solute that can be dissolved in a given amount of solvent at a specific temperature to form a saturated solution. It is usually expressed in grams of solute per 100 grams of solvent.

27) Fill in the blanks:-

Solution:
a) Atomic number forms the basis of the modern periodic table.
b) The chief ore of Aluminium is Bauxite (Al₂O₃·2H₂O).
c) Assertion: Magnesium is used to protect steel from rusting. Reason: Magnesium is more reactive than iron.
i) A and R are correct. R explains the A (This is a form of sacrificial protection where the more reactive metal, magnesium, corrodes instead of iron).

28) Differentiate the following: aerobic and anaerobic respiration.

Solution:
Feature Aerobic Respiration Anaerobic Respiration

29) List out the parasitic adaptation in leech.

Solution: Parasitic adaptations of the leech (Hirudinaria) include:
  1. Suckers: It has an anterior and a posterior sucker, which help in attachment to the host's body.
  2. Jaws and Teeth: The mouth, located in the anterior sucker, is equipped with three jaws bearing minute teeth, which make a painless Y-shaped incision in the host's skin.
  3. Anticoagulant (Hirudin): Its saliva contains hirudin, a substance that prevents the host's blood from clotting, ensuring a continuous supply of blood.
  4. Sanguivorous Nature: It is adapted to feed on blood. Its alimentary canal is designed to store large quantities of blood, which is digested slowly over several months.
  5. Anaerobiosis: It can respire anaerobically, which is an adaptation for its life in water where oxygen levels might be low.

30) State whether true or false.

Solution:
a) The phloem is responsible for the translocation of food. - True.
b) When guard cells lose water the stomata opens. - False. (When guard cells lose water, they become flaccid and the stomata close).
c) Bring out any two physiological activities of abscisic acid? - The activities are:
  1. Promotes Dormancy: It induces dormancy in buds and seeds, helping them survive unfavourable conditions.
  2. Controls Stomatal Closure: During water stress (drought), Abscisic acid (ABA) signals the guard cells to close the stomata, thus reducing water loss through transpiration.

31) Enumerate the functions of blood.

Solution: The main functions of blood are:
  1. Transport: It transports oxygen from the lungs to the tissues, carbon dioxide from the tissues to the lungs, digested food (nutrients) from the small intestine to all body cells, and waste products (like urea) to the kidneys for excretion. It also transports hormones from endocrine glands to target organs.
  2. Protection (Defense): White blood cells (leukocytes) defend the body against infections by engulfing pathogens (phagocytosis) or by producing antibodies. Platelets (thrombocytes) help in blood clotting to prevent excessive blood loss from injuries.
  3. Regulation (Homeostasis): Blood helps regulate body temperature by distributing heat. It also maintains the body's pH and water balance.

32) (Compulsory) a) Identify the bond between H and F in HF molecule. b) What property forms the basis of Identification? c) How does the property vary in periods and in groups?

Solution:
a) Bond in HF: The bond between Hydrogen (H) and Fluorine (F) in the HF molecule is a polar covalent bond.
b) Basis of Identification: The property that forms the basis for identifying this bond type is the difference in electronegativity between the two atoms. Fluorine is the most electronegative element, and hydrogen has a much lower electronegativity. This large difference causes the shared pair of electrons to be pulled closer to the fluorine atom, creating partial negative (δ-) and positive (δ+) charges.
c) Variation of Electronegativity:
  • In a Period (left to right): Electronegativity generally increases across a period because the nuclear charge increases while the atomic radius decreases, leading to a stronger attraction for bonding electrons.
  • In a Group (top to bottom): Electronegativity generally decreases down a group because the number of electron shells increases, which increases the atomic radius and the shielding effect, thus weakening the nucleus's attraction for bonding electrons.

33) What are the types of inertia? Give an example for each.

Types of Inertia with Examples

Inertia is the inherent property of a body to resist any change in its state of rest or of uniform motion. It is classified into three types:
  1. Inertia of Rest:
    • Definition: The tendency of a body to resist any change in its state of rest. A body at rest will remain at rest unless an external force acts on it.
    • Example: When you shake the branches of a tree vigorously, the fruits and leaves fall down. This is because the branches come into motion, but the fruits and leaves tend to remain at rest due to inertia of rest. Hence, they get detached.
  2. Inertia of Motion:
    • Definition: The tendency of a body to resist any change in its state of uniform motion. A body in motion will continue to move with the same velocity unless an external force acts on it.
    • Example: When a passenger jumps out of a moving bus, they tend to fall forward. This is because their feet come to rest upon touching the ground, but the upper part of their body continues to move forward due to inertia of motion.
  3. Inertia of Direction:
    • Definition: The tendency of a body to resist any change in its direction of motion.
    • Example: When a car takes a sharp turn at high speed, the passengers inside are pushed sideways. This happens because the car changes its direction, but the passengers' bodies tend to continue moving in the original straight-line path due to inertia of direction.

Derive the ideal gas equation.

The ideal gas equation is derived by combining three fundamental gas laws: Boyle's Law, Charles's Law, and Avogadro's Law.

1. Boyle's Law: At constant temperature (T) and number of moles (n), the volume (V) of a gas is inversely proportional to its pressure (P).

V ∝ 1/P .......... (Equation 1)

2. Charles's Law: At constant pressure (P) and number of moles (n), the volume (V) of a gas is directly proportional to its absolute temperature (T).

V ∝ T .......... (Equation 2)

3. Avogadro's Law: At constant temperature (T) and pressure (P), the volume (V) of a gas is directly proportional to the number of moles (n).

V ∝ n .......... (Equation 3)

Combining the three laws: By combining equations (1), (2), and (3), we get:

V ∝ (1/P) × T × n

V ∝ nT/P

To replace the proportionality sign (∝) with an equality sign (=), we introduce a constant of proportionality, R, which is called the Universal Gas Constant.

V = R (nT/P)

Rearranging the equation, we get the Ideal Gas Equation:

PV = nRT

This equation relates the pressure, volume, temperature, and number of moles of an ideal gas. The value of R is approximately 8.31 Jmol⁻¹K⁻¹.

34) a) Give the salient feature of "Modern atomic theory". [5 marks] b) Calculation of molecular mass of CO₂. [2 marks]

a) Salient Features of Modern Atomic Theory

The Modern Atomic Theory is an updated version of Dalton's atomic theory, incorporating new discoveries about the subatomic structure. Its key features are:
  1. Atom is no longer indivisible: An atom is now known to be divisible and consists of subatomic particles: protons, neutrons, and electrons.
  2. Atoms of the same element may have different atomic masses: The existence of isotopes proves this. Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons (e.g., ¹²C, ¹³C, ¹⁴C).
  3. Atoms of different elements may have the same atomic mass: The existence of isobars proves this. Isobars are atoms of different elements with the same mass number but different atomic numbers (e.g., Argon-40 and Calcium-40).
  4. An atom is the smallest particle that takes part in a chemical reaction: While atoms are divisible, they are the fundamental units involved in chemical combinations.
  5. The mass of an atom can be converted into energy: This is described by Einstein's equation, E = mc², which states that mass and energy are interconvertible. This is not observed in ordinary chemical reactions but is significant in nuclear reactions.
  6. Atoms may not always combine in simple whole-number ratios: In some non-stoichiometric compounds, the ratio of atoms is not simple (e.g., in some metal oxides and sulfides). However, for most compounds, the law of definite proportions still holds.

b) Calculation of Molecular Mass of CO₂

To calculate the molecular mass of Carbon Dioxide (CO₂), we need the atomic masses of Carbon (C) and Oxygen (O).
  • Atomic mass of Carbon (C) = 12.011 u (approx. 12 u)
  • Atomic mass of Oxygen (O) = 15.999 u (approx. 16 u)
The molecule CO₂ contains one Carbon atom and two Oxygen atoms.

Molecular Mass of CO₂ = (1 × Atomic mass of C) + (2 × Atomic mass of O)

= (1 × 12) + (2 × 16)

= 12 + 32

= 44 u

Therefore, the molecular mass of carbon dioxide is 44 u (atomic mass units).

Write note on Various factors affecting solubility.

Solubility is the ability of a solute to dissolve in a solvent. It is influenced by several factors:
  1. Nature of the Solute and Solvent:
    • The principle "like dissolves like" is a key determinant.
    • Polar solutes (like common salt, NaCl) dissolve in polar solvents (like water).
    • Non-polar solutes (like grease or oil) dissolve in non-polar solvents (like benzene or carbon tetrachloride).
    • A polar solute will not dissolve in a non-polar solvent and vice versa.
  2. Temperature:
    • Solubility of Solids in Liquids: For most solid solutes, solubility increases as the temperature increases (an endothermic process). For example, more sugar can be dissolved in hot water than in cold water. However, for some substances like cerium sulphate (Ce₂(SO₄)₃), solubility decreases with an increase in temperature (an exothermic process).
    • Solubility of Gases in Liquids: The solubility of gases in liquids generally decreases as the temperature increases. This is why dissolved oxygen levels are lower in warm water, and why carbonated drinks go "flat" more quickly when warm.
  3. Pressure:
    • Solubility of Solids in Liquids: Pressure has a negligible effect on the solubility of solid or liquid solutes in a liquid solvent because they are largely incompressible.
    • Solubility of Gases in Liquids: According to Henry's Law, the solubility of a gas in a liquid is directly proportional to the pressure of the gas above the liquid. This is why carbonated beverages are bottled under high pressure to increase the solubility of CO₂ gas. When the bottle is opened, the pressure is released, and the gas escapes as bubbles.

35) With a neat labelled diagram explain the structure of a neuron. [Explanation -5, Diagram -2]

Structure of a Neuron

A neuron (or nerve cell) is the structural and functional unit of the nervous system. It is responsible for transmitting nerve impulses. A typical neuron consists of three main parts: the cyton (cell body), dendrites, and axon.

Diagram of a Neuron: Diagram of a Neuron (Nerve Cell) Explanation of Parts:
  1. Cyton (Cell Body or Soma):
    • This is the main part of the neuron, which contains a large, central nucleus and cytoplasm.
    • The cytoplasm contains characteristic, deeply stained particles called Nissl's granules (clumps of rough endoplasmic reticulum and ribosomes), which are involved in protein synthesis.
    • Other cell organelles like mitochondria and Golgi apparatus are also present.
  2. Dendrites:
    • These are short, branched, tree-like processes that project from the cyton.
    • Their primary function is to receive nerve impulses (signals) from other neurons or sensory receptors and transmit them towards the cyton.
    • The numerous branches increase the surface area for receiving signals.
  3. Axon:
    • This is a single, long, slender projection that arises from the cyton. It is much longer than the dendrites.
    • Its primary function is to carry nerve impulses away from the cyton to other neurons, muscles, or glands.
    • The axon is covered by a protective sheath called the myelin sheath, which is formed by Schwann cells. The myelin sheath acts as an insulator and speeds up the transmission of nerve impulses.
    • The myelin sheath is not continuous; it has gaps at regular intervals called the Nodes of Ranvier. The impulse jumps from one node to the next, a process called saltatory conduction.
    • The end of the axon branches into fine filaments called axon terminals or telodendria. Each terminal ends in a bulb-like structure called a synaptic knob, which contains neurotransmitters used to transmit the signal across a synapse to the next neuron.

With a neat labelled diagram describe the parts of a typical angiospermic ovule. [Diagram -2, Explanation - 5]

Structure of an Angiospermic Ovule

The ovule (or megasporangium) is the structure within the ovary of a flowering plant that contains the female gamete and, after fertilization, develops into a seed.

Diagram of an Ovule: Diagram of an Angiospermic Ovule Explanation of Parts:
  1. Funiculus (or Funicle): This is the stalk that attaches the ovule to the placenta inside the ovary.
  2. Hilum: This is the point of attachment of the funiculus to the body of the ovule. It represents the junction between the ovule and the funicle.
  3. Integuments: These are the one or two protective outer layers that surround the ovule. After fertilization, they develop into the seed coat.
  4. Micropyle: This is a small opening at the apex of the integuments. It is the primary site for the entry of the pollen tube into the ovule for fertilization.
  5. Nucellus: This is a mass of parenchymatous tissue that forms the main body of the ovule, enclosed by the integuments. It provides nourishment to the developing embryo sac.
  6. Chalaza: This is the basal part of the ovule, located directly opposite the micropyle, where the nucellus, integuments, and funiculus merge.
  7. Embryo Sac (Female Gametophyte): This is the most important part of the ovule, located within the nucellus. It contains the female reproductive cells. A mature embryo sac is typically 7-celled and 8-nucleate, consisting of:
    • Egg Apparatus (at the micropylar end): Comprises one egg cell (female gamete) and two supporting cells called synergids.
    • Antipodal Cells (at the chalazal end): Three cells with a nutritive role.
    • Central Cell: The large central cell containing two polar nuclei, which fuse to form the secondary nucleus before fertilization.

III. Answer any 10 questions. Question No.42 is compulsory. (10×5=50)

29) Discuss the main causes of the first world war?

The main causes of the First World War can be summarized by the acronym M.A.I.N:
  1. Militarism: An arms race began as countries built up their armies and navies. Germany, in particular, expanded its military, causing alarm in Britain and other nations. This created a climate of fear and suspicion.
  2. Alliances: Europe was divided into two hostile armed camps. The Triple Alliance consisted of Germany, Austria-Hungary, and Italy. The Triple Entente consisted of France, Russia, and Britain. These alliances meant that a conflict between two nations could quickly escalate into a continental war.
  3. Imperialism: European powers competed for colonies and economic influence in Africa and Asia. This competition for resources and markets created intense rivalry and conflict, particularly between Britain, France, and Germany.
  4. Nationalism: Intense pride in one's country led to aggressive foreign policies. In the Balkan region, Slavic nationalism, encouraged by Russia, threatened the Austro-Hungarian Empire. This "powder keg of Europe" was a major source of tension.
The immediate cause was the assassination of Archduke Franz Ferdinand, the heir to the Austro-Hungarian throne, by a Serbian nationalist in Sarajevo on June 28, 1914. This event triggered the alliance system and led to the outbreak of war.

32) Fill in the blanks

v) Governor of the state government surrender his resignation to The President.

33) a) Distinguish between: i) Western Ghats and Eastern Ghats ii) Agrobased industry and Mineral based industry
b) Give Reason: Mountains are cooler than the plain.

a) i) Western Ghats vs. Eastern Ghats
FeatureWestern GhatsEastern Ghats
ContinuityContinuous mountain range.Discontinuous, eroded by rivers.
HeightHigher, with an average elevation of 900-1600 meters.Lower, with an average elevation of 600 meters.
RiversOrigin of major peninsular rivers like Godavari, Krishna, Kaveri.Rivers like Mahanadi, Godavari, Krishna flow through them to the Bay of Bengal.
RainfallReceives heavy rainfall from the southwest monsoon.Receives comparatively less rainfall.

a) ii) Agro-based Industry vs. Mineral-based Industry
FeatureAgro-based IndustryMineral-based Industry
Raw MaterialUses plant and animal-based products as raw materials.Uses mineral ores as raw materials.
ExamplesCotton textiles, sugar, paper, vegetable oil, food processing.Iron and steel, cement, aluminium, machine tools.
Location FactorOften located near sources of raw material (farms).Often located near mining areas or ports for importing ores.

b) Reason: Mountains are cooler than the plain.
Mountains are cooler than plains due to a phenomenon called the "Normal Lapse Rate". As altitude (height above sea level) increases, the air becomes less dense. Thinner air is less capable of absorbing and retaining heat from the sun's radiation, causing the temperature to drop. The temperature decreases at an average rate of 6.5°C for every 1000 meters of ascent.

37) Explain the salient features of the constitution of India.
