1) The melting point of a solid is the temperature at which it changes state from solid to fluid.
2) Heat of fusion is the thermal energy which must be withdrawn to solidify a certain mass or quantity of fluid or added to melt a certain mass or quantity of solid. It is also called the latent heat of fusion or the enthalpy of fusion, and the temperature at which it occurs is called the melting point.
3) The boiling point of a substance is the temperature at which it can change state from a liquid to a gas throughout the bulk of the liquid.
4) Heat of evaporation describes the amount of energy in the form of heat that is required for a material to undergo a change of phase from fluid to gas.
