evaporation

the physical change when a liquid becomes a gas. Since such a change usually requires heat as an energy source, heat is drawn from the immediate environment, which produces a significant cooling effect. The size of the cooling effect depends on the latent heat of evaporation of the liquid. Evaporation of water is used by mammals in temperature regulation through sweating, and occurs in plants from the surface of the mesophyll cells during TRANSPIRATION.
