Question

Why are latent heat of codensation and evaporation different?

Answer 1

Hi friend,

First you have to understand the difference between fusion and vaporization process.

Fusion Process : It is the process of change of state from solid to liquid.

Vaporization: It is the process of change of state from liquid to vapour.

So

Latent heat of fusion is the amount of heat required to change phase from solid to liquid at constant temperature

while latent heat of vaporization is the amount of heat required to change phase from liquid to vapour at constant temperature.

Hope it helps..
