Brief Explanations:

A chemical reaction produces new substances with different chemical properties. Breaking glass, freezing water, cutting a tree, and evaporating alcohol are physical changes (no new substances form). Digestion breaks down food into new molecules (e.g., glucose from starch) via chemical reactions.
