Liquid changes into solid on cooling but the batter of a cake changes into a cake on heating in an oven. Why?
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:
