Explanation:

A physical change is a change in which no new substances are formed. Chopping firewood only changes the size and shape of the wood, but the chemical composition of the wood remains the same. A chemical change is a change in which new substances are formed. For example, when a metal pipe rusts, a new substance (rust) is formed.
