Question

27 george ate pizza yesterday, and his body digested it. is digestion a physical or chemical change?

Explanation:

Digestion involves breaking down food (like pizza) into simpler substances (e.g., nutrients) through processes like enzymatic reactions. These reactions create new substances (e.g., amino acids from proteins, sugars from carbohydrates), which is a key characteristic of a chemical change. Physical changes don't form new substances, but digestion does, so it's a chemical change.

Answer:

Digestion of pizza is a chemical change.
