Name______________________________________________ Date_________________________ Activity: Determining Types of Heat Transfer Cooking methods rely on dry heat, moist heat, and combination heat. Depending on the method used, heat transfer occurs through conduction, convection, or radiation. Conduction uses direct physical contact to transfer heat. Convection uses a medium surrounding the food such as hot air, hot water, or hot fat to transfer heat. Radiation transfers heat through heat waves. Identify the type of heat used (dry, moist, or combination) and explain how heat is transferred (conduction, convection, or radiation) for the following cooking methods. ������������������ 1. Poaching uses ___ heat. ������������������ 2. When poaching, heat is transferred through ___. ������������������ 3. Grilling uses ___ heat. ������������������ 4.
