While cookies are baking in the oven, heat transfer occurs to make them bake correctly. As said by the author Nora Fulmer, heat transfer is the process where an item comes into contact with a heat source and exchange thermal energy between two objects. It is a complex process that removes bacteria, while cooking food. Heat energy is created and transferred when food becomes hot, its molecules absorb energy and begin bouncing off each other. The first type of heat transfer is conduction. Conduction is the process where heat is transferred between objects by direct contact. Conduction is good for cooking because it allows food to be cooked from the outside in, however it is the slowest process of heat transfer. The second type of heat transfer
