Detailed explanation-1: -The change of a substance from its liquid state to its gaseous state at any temperature below its boiling point is called evaporation. During the process of evaporation, the liquids absorb heat from the surroundings which cause a cooling effect.

Detailed explanation-2: -As perspiration evaporates it absorbs heat to cool your body. The principle underlying evaporative cooling is the fact that water must have heat applied to it to change from a liquid to a vapor. When evaporation occurs, this heat is taken from the water that remains in the liquid state, resulting in a cooler liquid.
