The egg also begins to cook and harden, which is another chemical change. Heat causes protein from the egg to alter and make the cake company. This is because when cooked, the heat denatures the proteins which changes their properties and composition. However, the eggs chemical composition does not change. Heat assists baking powder produce tiny bubbles of gas that makes the cake light and fluffy. When an egg is raw, the proteins are separated by water molecules. Ice cream melting on a hot day is also a change in state. While a physical change can often be reversed, a chemical change typically cannot be, except through more chemical reactions.
