Question

Quizplus · Accepted Answer

Evaporation is the phase change of liquid to gas at the surface of the liquid, and it involves the latent heat of evaporation. The energy required to evaporate a given amount of water is absorbed as heat from the surroundings, and the temperature of the remaining liquid decreases due to the loss of high-energy molecules. The latent heat of evaporation is the amount of energy required to convert a unit mass of liquid into a unit mass of gas at constant temperature and pressure. This energy is used to overcome the intermolecular forces that hold the liquid molecules together and to provide kinetic energy to the escaping gas molecules.
