Is chewing a cookie a physical or chemical change?

Answer 1

Chewing food is not a chemical change, it is Physical. all you are doing is crushing down the food inside your mouth, not changing the actual substance.

Answer 2

It is both.

It is a physical change because when you chew your food you break it up into smaller pieces and are therefore changing its size and shape which are physical changes.
