As you bake a cake, you are producing an endothermic chemical reaction that changes ooey-gooey batter into a fluffy, delicious treat! … Heat helps baking powder produce tiny bubbles of gas, which makes the cake light and fluffy. Heat causes protein from the egg to change and make the cake firm.
Is baking a cake a chemical or physical change?
Baking a cake is a chemical change because the baking powder or baking soda will undergo a chemical reaction. The heat helps baking powder or soda produce tiny bubbles of gas which makes the cake light and fluffy. That’s why chemical reactions are involved in baking a cake.
Is mixing a cake a chemical change?

Is burning a chemical change?
Lighting a match and letting is burn is an example of a chemical change. Chemical reactions cause chemical changes. In a chemical reaction two or more substances, called the reactants, form different substances called products.
Why is baking bread a chemical change?
The trapped carbon dioxide makes the dough rise, and the alcohol evaporates during the baking process. This is an irreversible chemical change, because by consuming the sugar, the yeast has created new substances—carbon dioxide and ethanol—and the reaction cannot be reversed.
Is popping popcorn a chemical change?
