Bread baking in an oven.
Baking is a chemical change because new substances form (fermentation, Maillard browning, protein denaturation), and the change is not easily reversed. The others are physical changes (phase change or mechanical breakup) — evaporation, tearing, and cutting only change shape or phase, not chemical identity.
