Conduction of Heat Heat transfer through the process of conduction occurs in substances which are in direct contact with each other. Your question: Can you boil garlic with pasta? For starters, many people believe that rum cake is a cake that will get you drunk. The heat causes the bonds between the amino acids in the proteins to break, and as a result, new bonds are formed between different amino acids. A chemical change that gives off heat is called an exothermic reaction. The proteins in the egg white and the yolk denature, or change shape. The heat causes an irreversible chemical change to occur. Bubbles: Some chemical changes produce gases, which can be seen as bubbles in a liquid solution. One example of a chemical change that occurs when you cook is the denaturation of proteins.
