Answer 1

The main difference between chemical changes and physical changes is that chemical changes form new substances. In a chemical change, the composition of the substance is altered, resulting in the creation of different materials. Physical changes, on the other hand, do not alter the fundamental composition of the substance; they may involve changes in state (such as melting or boiling) but do not create new substances.
