Its a chemical change.
Chemical Reaction
Digesting a candy bar involves both physical and chemical processes. Physical processes include chewing and breaking down the food into smaller pieces, while chemical processes involve enzymes breaking down the food into smaller molecules that can be absorbed by the body.
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.
It's actually both, my science teacher and the class are talking about that.
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.
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.
It's actually both, my science teacher and the class are talking about that.
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.
yes
Food digestions involve many chemical reactions.
Mechanical digesting is this that involve physical breakdown or movement of food not chemical. Actions like chewing and swallowing would be mechanical.
