Conduction of Heat Heat transfer through the process of conduction occurs in substances which are in direct contact with each other. This is what gives caramel its distinctive flavor. Answer. There are several different ways to cook an egg, but the basic chemical equation for all of them is the same: heat causes the proteins in the egg to denature, and that makes the egg solidify. Also, eggs lose up to 12.5% of water during frying. In this case many of the bonds broken are those which trigger the eggs proteins to be folded into a globular shape. It probably has to do with the fact that some chemical changes also occur when you cook an egg.
