Completely digesting a sandwich is not considered a physical change; it is a chemical change. During digestion, the food undergoes various chemical reactions, breaking down complex molecules into simpler ones, such as proteins into amino acids and carbohydrates into sugars. This process alters the chemical composition of the food, distinguishing it from physical changes, which do not affect the chemical structure.
1. First step: a physical change 2. Second step: a chemical change
Digesting french fries is both a physical and a chemical change. The chewing, pressing, and manipulating of the french fry is physical. The enzymes, bacterias, and acids breaking them down would be chemical.
Chemical Change
Digesting a banana is a chemical reaction, an ireversible change.
Growing taller. All the others are cosmetic changes.
yes
Its a chemical change.

Digesting a sandwich would not be considered a physical change because it involves a chemical process where the food is broken down into smaller molecules by enzymes in the digestive system. This process leads to the absorption of nutrients into the bloodstream rather than just a change in physical appearance or state.
It's actually both, my science teacher and the class are talking about that.
Chemical Change
Digesting French fries is a chemical change because the process involves breaking down the molecules in the food through enzymes and acids in the stomach to extract the nutrients for absorption into the body. This results in a change in the chemical composition of the food.

Digesting food is a very good example of a chemical change. However, it is also a common example of a physical change with the body.
