Question

What is latent heat of fusion and vaporization?

Answer 1

Latent heat of fusion-The amount of heat energy required to change 1 kg of solid into liquid at its melting point is called the latent heat of fusion of the solid. Latent heat of vaporisation-The amount of heat energy required to change 1 kg of liquid into vapour at atmospheric pressure at its melting point is called the latent heat of vaporisation of the liquid.

Answer 2

LATENT HEAT OF FUSION -

Latent heat of fusion is the change of enthalpy or heat by which any substance in specific quantity to change its state.It is also known as enthalpy of fusion.

LATENT HEAT OF VAPORIZATION-
Latent heat of vaporization is the process in which phase of liquid changes from liquid to vapor when external energy or heat is given to liquid .
