A physical change is a change that affects the appearance but not the chemical makeup of a substance.[1]

Some examples include changes in the state of matter: melting (solid to liquid), evaporation (liquid to gas) and sublimation. Many times, dissolution is also a physical change, such as when salt is dissolved, as the water can be evaporated.
