WebEvaporative Cooling: As water evaporates off the surface of an object, the faster moving molecules, with more kinetic energy, escape as a gas, while the lower energy molecules, with less kinetic energy, remain as liquid. This lowers the temperature on the surface from which the liquid is evaporating. Sweating is a form of evaporative cooling.
