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.

Which type of change is evaporation?

The evaporation of water is a physical change. When water evaporates, it changes from the liquid state to the gas state, but it is still water; it has not changed into any other substance. All changes of state are physical changes.

What change occurs during evaporation?

In evaporation, matter changes from a liquid to a gas. In condensation, matter changes from a gas to a liquid. All matter is made of tiny moving particles called molecules.
