Final answer:

A chemical reaction changes substances into new ones through rearrangement of atoms.


Explanation:

A chemical reaction involves the rearrangement of atoms to form new substances with different properties. In this context, the digestion of food is a chemical reaction because it involves breaking down complex molecules into simpler ones, releasing energy. On the other hand, breaking a glass pane, freezing water, cutting down a tree, and evaporation of rubbing alcohol are physical changes as they do not involve the formation of new substances.
