Solution

a. The latent heat is the hidden heat that is used up to overcome the interparticle force of attraction.

b. Latent heat of fusion of ice:
The latent heat of fusion is the amount of heat in joules that is required to convert 1 kg of ice into the water at its melting point and atmospheric pressure without any change of temperature. Its value is $3.34 x 10^{5} J / k g .$

Latent heat of vaporisation of water
The latent heat of vaporisation is the amount of heat in joules that is required to convert 1 kg of water into the water vapour at its boiling point and atmospheric pressure without any change of temperature. Its value is $22.5 x 10^{5} J / k g .$
