Question 11.

Answer the following:

Explain the role of latent heat in the change of state of a substance?


Answer:

The role of latent heat in the change of state of a substance are:


⇒ Latent heat of fusion: The latent heat of fusion helps to transform any substance from solid state to liquid state by absorbing heat energy at constant temperature during transformation.


⇒ Latent heat of vaporization: The latent heat of vaporization helps to transform any liquid substance from liquid state to gaseous state by absorbing heat energy at constant temperature during transformation.
