Answer:
1. The amount of heat energy is absorbed at constant temperature by units mass of solid to liquid phase is called latent heat of fusion.
2. Same as first.
3. Same till mass of liquid to gaseous phase is called latent heat of vaporisation.

(1) [tex]\bf\large\underline\green{Latent \:heat \:of \:fusion}[/tex] is the amount of heat that must be given to a substance a constant temperature to change its state from solid to liquid.
(2) Latent heat of fusion per unit mass of a substance is called its [tex]\bf\large\underline\green{specific \:latent \:heat \:of \:fusion}[/tex].
(3) [tex]\bf\large\underline\green{Latent \:heat \:of \:vaporisation}[/tex] is the amount of heat that must be given to a substance at a constant temperature to change its state from liquid to vapour.
