Cooking the egg is an example of a chemical change.


A chemical change means that something is permanently changed and there's no way to get it back. The proteins in the egg white/yolk are subjected to high heat, they change into varying proteins.

If it was the breaking of the egg that would be a Physical change, as everything about the egg would be the same (proteins, yolk)
