That's correct! In a physical change, the form or appearance of a substance changes, but its chemical composition remains the same. This means that the substance retains its inherent properties, and no new substances are formed. Common examples of physical changes include:
- Melting of ice into water
- Boiling water into steam
- Dissolving sugar in water
- Breaking a glass
In each of these examples, while the state or appearance of the material may change, the molecules and their chemical structure remain unchanged.
