Is scrambled eggs a physical or chemical change?

A scrambled egg before heat is applied is still a raw egg, the white and yolk are just interspersed. That’s a physical change. Once heat is applied, reactions occur, and most of the egg changes from liquid to solid. It is no longer a raw egg and there is no way to separate the product into its former constituents.

What kind of chemical change is cooking an egg?

Cooking an egg is a chemical change. This is because when cooked, the heat denatures the proteins which changes their properties and composition.

Is cooking an egg endothermic or exothermic?

Cooking of an egg is an endothermic reaction. Cooking is the art , technology , science and craft of using heat to prepare food for consumption. An endothermic reaction occurs when energy is absorbed from the surroundings in the form of heat. In this case heat energy is absorbed from the pan to the egg.

What happens when you cook an egg?

Denaturation is what happens when heat is applied to the eggs. … The heat coming from your stove denatures the protein by disrupting some of its bonds that held the molecule into shape. In the case of hard-boiled eggs, the proteins clump together and solidify, causing the egg white and yolk to harden.
