The transformation of dough into bread involves both physical and chemical changes. The physical changes include the expansion of the dough during baking due to the release of gases, while the chemical changes involve the reactions between proteins and starches in the dough leading to the formation of a stable bread structure.
Is yeast causing bread to rise is a physical or chemical change?
