Question

Explain the latent heat of fusion and
latent heat of vaporisation.​

Answer 1

Fusion Process : It is the process of change of state from solid to liquid. ... while latent heat of vaporization is the amount of heat required to change phase from liquid to vapour at constant temperature.

Answer 2

Answer:

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.

Latent Heat Of Fusion Of Ice

It is the heat required to convert one gram of ice at 0 degree C into one gram of water at 0 degree C Latent heat of fusion Of ice is 80 cal/g

Latent Heat of Vaporization of Water

It is the amount of heat required to convert one gram of water at 100 degree C into one gram of vapour at 100 degree C

Latent Heat of Vaporization of Water is

536 cal/g

The former deals with conversion of water into into ice and vice versa whereas the later deals with the conversion of water into vapour and vice versa
