Answer
Your understanding is correct!
- A physical change is a change in the form or appearance of a substance, but not its chemical composition. The substance remains chemically the same.
- Example: Melting ice into water. It's still H₂O, just in a different state.
- A chemical change (or chemical reaction) results in the formation of new substances with different chemical properties. The original substances are transformed into entirely new ones.
- Example: Burning wood. The wood changes into ash, smoke, and gases, which are new substances.
