Is cooking an egg a chemical change physical change neither both?
Cooking an egg is a chemical change. This is because when cooked, the heat denatures the proteins which changes their properties and composition. If using eggs instead of other options as a bonding material in baking, any property or state recognisable as an egg is lost.
Is boiling an egg a physical or a chemical change explain your answer?
Boiling an egg is a chemical reaction. The heat taken in by the egg causes permanent changes to the molecular structure of the egg, creating a new…
Why cooking an egg is an endothermic reaction?
Cooking an egg is an endothermic process because added energy makes it cooked. An egg without heats stays an (uncooked) egg. In this reaction, energy is absorbed. In an exothermic reaction, energy is released.
Is frying an egg a chemical or physical change?
Yes, frying an egg is a chemical change because it results in the formation of new particles. The heat in the frying process gives energy to the egg’s molecules and brings about a permanent change in the substance.
Is breaking an egg a chemical or physical change?
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. But since you’re only breaking the egg,…

Breaking an egg is a physical change. We still have shell (but broken in pieces now) and we still have egg yolk and egg white bit those are now outside th shell. Cooking an egg is a chemical change. We have changed the chemical composition of the yolk an the egg white.
Is cooking food a chemical change or physical?
Cooking of food is a chemical process since it involves changes in the chemical composition of food. Heating food at high temperature and adding additives such as oil, butter, baking powder etc results in the breaking down of chemical substances present in food and formation of new chemical substances.
