Is breaking an egg an example of a physical or chemical change? explain your answer. b. is cooking an egg an example of a physical or chemical change? explain your answer?

Breaking an egg is an example of a physical change. This is because the egg was broken, thus its physical appearance was different. If you were to cook the egg, that would be a chemical change because that would result in a new chemical formation of the stuff inside of the egg.
