Examples of convection heating
WebSep 28, 2024 · In the culinary arts, the term convection refers to a method of heat transfer where food is heated by a moving heat source such as hot air inside an oven that is circulated by a fan. The movement of steam or the motion of boiling water in a pot are also examples of convection. Because convection circulates heat, it accelerates the … WebConduction is one of the three main ways that heat energy moves from place to place. The other two ways heat moves around are radiation and convection. Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. Conduction occurs more readily in solids and liquids, where the particles ...
