Is baking a cake from mixture of flour sugar eggs milk and chocolate physical or chemical change?

Explanation:

Baking a cake involves a series of chemical reactions that transform the raw ingredients (flour, sugar, eggs, milk, and chocolate) into a cake. During baking, the heat causes the ingredients to undergo various chemical changes, such as the denaturation of proteins, gelatinization of starch, caramelization of sugars, and Maillard reaction. These reactions result in the formation of new substances with different properties, giving the cake its characteristic texture, color, and flavor. Therefore, baking a cake is considered a chemical change.
