What is the difference between specific latent heat of fusion and specific latent heat of vaporisation?

Ans. The amount of heat energy absorbed at constant temperature by unit mass of a solid to convert into liquid phase is called the specific latent heat of fusion, whereas, amount of heat energy absorbed at constant temperature by unit mass of a liquid to convert into gaseous phase is called the specific latent heat of vaporisation.
