It is a chemical change. because starch present in bread is converted into carbon and carbon dioxide and reverse of the process is not possible.
Slicing bread is a physical change because it does not change the chemical composition of the bread.

Burning toast would be a chemical change. The bread would be changed into carbon and the reaction can not be reversed.
Slicing bread is a physical change because it does not change the chemical composition of the bread.
Burning bread is a chemical change. It involves a chemical reaction between the bread and oxygen in the air, resulting in the formation of new substances such as carbon dioxide and water vapor. This change is irreversible and produces a color and chemical composition different from the original bread.
bread is a chemical change, not a physical change
Slicing bread is a physical change, because each slice of bread has the same chemical composition as it had before it was sliced.
Yeast rising bread works because yeast (an organism) converts starch to carbon dioxide which makes bread grow. This can be seen as a chemical reaction (yeast converting starch to CO2 gas) or a physical reaction (the CO2 making the bread expand).

No, slicing bread is a physical change. The act of cutting the bread into smaller pieces does not alter its chemical composition.
