Question

2. Digestion of food is physical change.​

Answer 1

Explanation:

When food is physically changed, mechanical digestion occurs. Food is broken into smaller parts and mixes continually with enzymes and other gastric juices. Mechanical digestion occurs in the mouth, stomach, and small intestine. Food is chemically changed in digestion when new, smaller substances are formed.

Answer 2

Answer:

Digestion is considered a physical and chemical change because enzymes in the stomach and intestines break down large macromolecules into simpler molecules so that the body can more easily absorb the food. ... So, water freezing to ice or boiling to steam is a physical change, not a chemical one.
