Any form of digestion is a chemical reaction. It begins when you chew with the saliva in your mouth and continues all the way down to your intestine. Bread, which contains mostly starches, is converted into sugars, which in turn provide your body with energy. This is why runners and other athletes sometimes eat pasta the night before they have an event.
Toasting bread is a chemical change because the heat causes chemical reactions to occur within the bread, leading to a browning effect and changing the chemical composition of the bread.
Slicing bread is a physical change because it does not change the chemical composition of the bread.
Its a chemical change because its changing what it is (from dough to bread)

Toasting bread is a chemical change because the heat causes a chemical reaction in the bread, leading to the browning and change in flavor. This involves the Maillard reaction, where the sugars and amino acids in the bread react to form new compounds.
No, slicing bread is a physical change. The act of cutting the bread into smaller pieces does not alter its chemical composition.

Bread going moldy is a chemical change
Bread is not a change. It is a mixture of substances that can undergo physical and chemical changes.

Making toast is a chemical reaction because you can't change it back into untoasted bread.The drying of the bread is physical but the actual caramelization or darkening of the outer bread layer is a chemical change. The outer edges of the bread are beginning to char. Generally, a color change is an indicator of a chemical change.
bread is a chemical change, not a physical change
