Yes because once you bake the bread you cannot change the substance back to unbaked bread.
Chemical.
bread is a chemical change, not a physical change
Its a chemical change because its changing what it is (from dough to bread)
This is a chemical change.
yes it involves some chemical reactions by yeast
Classify it as chemical, the heat is used mainly to speed up the reaction.

Baking dough into bread is a chemical change because the heat causes chemical reactions to occur in the dough, leading to the formation of new substances such as carbon dioxide and water vapor, resulting in the transformation of the dough into bread.
Baking bread is an exothermic process. During baking, heat is applied to the dough causing chemical reactions to occur, such as the Maillard reaction and caramelization, which release heat energy in the form of steam and heat, resulting in the bread rising and forming a crust.
Baking bread is primarily an endothermic process, as it requires the absorption of heat to cook the dough and facilitate the chemical reactions involved in fermentation and starch gelatinization. During baking, heat is transferred into the bread, causing it to rise and develop its texture and flavor. While there may be some exothermic reactions occurring, such as the Maillard reaction during browning, the overall process of baking bread is considered endothermic.
The reaction of baking powder in biscuit and bread dough is a chemical change. When baking powder is mixed with moisture and heat, it undergoes a chemical reaction that produces carbon dioxide gas. This gas forms bubbles in the dough, causing it to rise. Unlike physical changes, which do not alter the chemical composition of a substance, this reaction fundamentally transforms the ingredients involved.
