Explanation:

A chemical change is characterized by the formation of a new substance. When batter is cooked to make a pancake, a new substance (the pancake) is formed. A change in state of matter (e.g., solid - liquid - gas) is a physical change. If a change can be reversed, it is often a physical change. A change in shape is also a physical change.

C. A new substance forms when the batter is cooked.
