Is baking a cake a chemical change? Next time you bake a cake, think about this: The cake dough isn't really a cake, but when it's heated in the oven, a chemical reaction occurs and new bonds are formed. How does heat change things? It creates chemical reactions. When it comes to heat and baking, there are two types of chemical reactions to consider; one is “exothermic,” a reaction that produces heat, and the other is “endothermic,” a reaction that takes heat in. As you bake a cake, you are producing an endothermic chemical reaction that changes ooey-gooey batter into a fluffy, delicious treat!
A few things can happen when you bake a cake. Some chemical reactions to keep in mind while doing this tasty experiment are:
- 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.
- Oil keeps the heat from drying out the cake.
