Answer 1

The melting of chocolate chips is an indicator of a physical change. When chocolate chips melt, they change from a solid to a liquid state without altering their chemical composition. In contrast, the baking of the cookie ingredients together leads to chemical changes, as new substances are formed during the process. Therefore, the correct response is:

**Chocolate chips melting**
