Physical changes are ones which do not affect the chemical composition of a substance. For instance, if you cut a cake in half, that is a physical change. Nothing has changed except the shape, weight, and size of the cake. When you bake the cake batter, however, you are causing a chemical change. The batter changes into a cake; when you cut the cake, it doesn't change into anything.
