Physical changes of matter involve alterations in the state or appearance of a substance without changing its composition. Four common examples include: 1. Freezing - liquid to solid; 2. Melting - solid to liquid; 3. Evaporation - liquid to gas; and 4. Condensation - gas to liquid. These changes are reversible, and the substance retains its original properties.
