This process of cooling the molten polymer is characterized by heat transfer through convection. WebSep 30, 2016 · September 30, 2016 at 6:15 am. 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. rthawk
