the mass of the substance changes.
the state of the substance changes.
atoms of one or more substances rearrange into a new substance.

Explanation:

In a physical change, the substance remains the same chemically, just its appearance or state may change. In a chemical change, atoms of substances rearrange to form new substances. Mass is conserved in both physical and chemical changes. Appearance and state changes can occur in physical changes. So, the key difference is the rearrangement of atoms to form new substances in chemical changes.

Answer:

Atoms of one or more substances rearrange into a new substance.
