Physical changes occur when a substance changes its form, but the chemical composition remains the same. This means that you end up with the same molecules and atoms as you started with. When a chemical change occurs, the chemical composition of the substance changes, meaning that new molecules and atoms are created. Some physical changes can be reversed, such as melting an ice cube, but chemical changes are usually irreversible, such as burning a piece of paper.
