Answer:

No, burnt bread has undergone a chemical change. Toasting bread is a chemical change. Adding heat to the bread cooks it, changing it on a molecular level

Explanation:

Many physical changes are reversible (such as heating and cooling), whereas chemical changes are often irreversible or only reversible with an additional chemical change.
