Chewing a piece of bread in the mouth for two minutes involves both physical and chemical processes. Physically, chewing breaks the bread into smaller pieces, increasing its surface area. Chemically, enzymes in saliva, like amylase, begin to break down the starches in the bread into simpler sugars. Therefore, it is a combination of both physical and chemical changes.
