WebHeat energy can be transferred from areas of high energy to areas of lower energy by conduction, convection and radiation. Understanding how to control these processes helps reduce energy consumption. Heat moves naturally by any of three means. The processes are known as conduction, convection and radiation. Sometimes more than one may occur at the same time. First, a little background. All matter is made from atoms — either single ones or those bonded in groups known as molecules. These atoms … See more Put a pan on a stovetop and turn on the heat. The metal sitting over the burner will be the first part of the pan to get hot. Atoms in the pan’s bottom will start to vibrate faster as they … See more Convection occurs when a material is free to move, such as a liquid or a gas. Again, consider a pan on the stove. Put water in the pan, then turn on the heat. As the pan gets hot, some of that heat transfers to the molecules of water … See more The third type of energy transfer is in some ways the most unusual.
