Changes of state are considered physical changes because?
Physical changes are changes that don't change the structure of the individual molecules. Though heating a liquid to a gas will change how the molecules are bound to each other, the individual molecules will not change. This is contrasted from a chemical change, where the atoms of the molecules are rearranged.
