In this activity, you will explore the energy change that accompanies the process of evaporation. Evaporation, like melting or freezing, is an example of a phase change—a change from one physical form of a substance to another.. During evaporation, energetic molecules leave the liquid phase, which lowers the average energy of the remaining liquid molecules.
