While deciding the unit for heat, which temperatures interval is chosen? Why?

Question 4.

While deciding the unit for heat, which temperatures interval is chosen? Why?

Answer:

While defining the unit for heat, the temperature range between 14°C to 15.5°C is chosen.

If we take different temperature range than 14°C to 15.5°C, the amount of heat required will be slightly different. It is, therefore, essential to define a specific temperature range while. defining the unit of heat.
