Question

describe latent heat of fusion and latent heat of vaporization

Answer 1

The enthalpy of fusion of a substance, also known as (latent) heat of fusion, is the change in its enthalpy resulting from providing energy, typically heat, to a specific quantity of the substance to change its state from a solid to a liquid, at constant pressure.
Latent heat of vaporization is a physical property of a substance. ... When a material in liquid state is given energy, it changes its phase from liquid to vapor; the energy absorbed in this process is called heat of vaporization.

Answer 2

heya frnd

amount of heat needed to change a mass of 1 kg the substance from a solid at its melting point into liquid at the same temperature is latent heat of fusion

amount of heat required to convert unit mass of liquid into its vapour state without change in its temperature called is latent heat of vaporization.
