Chemical and Physical Changes:

Physical Changes:
- A physical change is a change in which the substance's form or appearance changes, but its chemical composition remains the same.
- Examples of physical changes include melting, freezing, boiling, cutting, and crushing.
- These changes are usually reversible, meaning the substance can return to its original state.

Chemical Changes:
- A chemical change is a change in which a substance undergoes a chemical reaction and forms a new substance with different chemical properties.
- Examples of chemical changes include burning, rusting, and digestion.
- These changes are usually irreversible, meaning the original substance cannot be easily recovered.
