Question

Which of the following is correct for a speccific latent heat of a substance?

• A. Random rise in temperature.
• B. Change in phase without rise in temperature.
• C. Change in phase with rise in temperature by unity
• D. No change of phase with rise in temperature.

Answer 1

The correct option is B

Change in phase without rise in temperature.

Specific latent heat is the amount of heat supplied to a substance to change its state without rise in temperature. The chage of ice at 0 degrees to water at 0 degrees is an example of specific latent heat where the provided heat is utilized in breaking the bonds of ice to convert it to water at the same temperature.
