which is an example of a chemical change?
water evaporating from a puddle
cloth tearing when pulled
wood forming sawdust when cut
bread baking in an oven

Explanation:

A chemical change produces a new substance with different chemical properties, while physical changes only alter the form/state of matter without changing its chemical identity. Water evaporating, cloth tearing, and wood turning to sawdust are all physical changes (no new substance is formed). Baking bread involves reactions like Maillard browning and yeast fermentation that create new chemical compounds, making it a chemical change.

bread baking in an oven
