Step-by-step explanation:

These are the examples that best correspond with the descriptions. In chemistry, it is important to distinguish between chemical and physical changes. A chemical change is one that produces a new substance. On the other hand, a physical change is one in which the material may change shape or form, but no chemical reactions occur and no new compounds are produced.
