Question

Two friends are discussing physical and chemical changes. Isabela says that when you eat, it is a physical change because when you chew, the food is only changed into smaller pieces. Mirabel says that when you eat, it is a chemical change because your body digests the food as the chemicals in your body break down the food into energy. Who is right?(1 point)

Both girls are correct.

Chewing is a physical change (mechanical breakdown into smaller pieces), while digestion is a chemical change (enzymes break down molecules like starches and proteins into new substances the body can absorb).
