Question

Define latent heat of vaporisation/fusion

Answer 1

 latent heat of fusion: the amount of heat energy that is required to change 1 kg of solid into liquid at atmospheric pressure at its melting point is known as the latent heat of fusion.



hope it helps...

Answer 2

Mr singh here is ur ans:-

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.
