latent heat of fusion in the amount of heat energy needed to convert 1 kg of a solid into liquid state at its melting point without any rise in temperature . while latent heat of vaporization is the amount of heat energy to convert 1 kg of liquid into vapour state its boiling point without any rise in temperature

Answer:
Latent heat of vaporization is defined as the heat required to change one mole of liquid at its boiling point under standard atmospheric pressure.
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 a constant pressure.
