The heat from the pan causes the proteins in the egg to denature, or change shape, and this results in a cooked egg. Others believe that it is endothermic, meaning that it consumes heat. In a raw egg, these proteins are curled and folded to form a compact ball. When you fry an egg, the protein in the egg changes shape and the egg becomes solid. The shell is made up of calcium carbonate and protects the egg from bacteria. Other modifications of state include vaporization (liquid to gas), freezing (liquid to strong), and condensation (gas to liquid). How do you know when sourdough bread is done baking. These collisions break the weak bonds that held the protein globs curled up, allowing the amino acid chains to partly unwind a process called denaturing. Cooking an egg is a physical change.
