Final answer:

Melting butter and forming rust are physical changes, while turning wood into ash is a chemical change.

Explanation:

Physical change: Melting butter in a microwave is a physical change as the butter changes from a solid to a liquid state without altering its chemical composition.

Chemical change: Turning wood into ash involves a chemical change as the wood undergoes combustion to form new substances like carbon dioxide and ashes.

Physical change: Leaving metal outside in the rain until rust forms is a physical change as it involves the metal surface forming a new layer of iron oxide without a change in its chemical composition.
