WebWhich statement describes the direction of spontaneous heat flow C) heat flows from high temperature to low temperature how are refrigerants used to removed heat in a refrigerator A) The refrigerant vaporizes as it absorbs heat from the food Throughout the universe, it’s natural for energy to flow from one place to another. And unless people interfere, thermal energy — or heat — naturally flows in one direction only: from hot toward cold. Heat moves naturally by any of three means. The processes are known as conduction, convection and radiation. 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 … See more The third type of energy transfer is in some ways the most unusual.
