5- Minute Quiz: PHYSICAL VS. CHEMICAL CHANGES

In a physical change, the appearance or form of the matter changes but the kind of matter in the substance does not. However, in a chemical change, the kind of matter changes, and at least one new substance with new properties is formed.

Examples of chemical changes are burning, cooking, rusting, and rotting. Examples of physical changes are boiling, melting, freezing, and shredding. Often, physical changes can be undone, if energy is input. The only way to reverse a chemical change is via another chemical reaction.
