In contrast, there are two mechanisms of heat transfer (conduction and radiation) that refer to the physical phenomena that give rise to the energy transfer. The mode of heat transfer by convection is based on a conduction mechanism. A thermal channel is defined as a "pathway" for heat to ...
This is called heat transfer. (Remember, we learned that energy transfer is when energy moves from one thing or place to another, but the energy type stays the same). Heat can transfer (or move) in 3 ways: conduction, convection, and radiation. As you read about the three types of hea...

传导传热(heattrasferbyconduction) 依靠构成物质的粒子(原子、分子或电子)以平衡位置为中心的运动,把热量从物体的高温端传到低温端的传热方式。可在固体与静止的流体中发生。热传导的基本公式为`bb{q}=-lambda*nablaT`,传热的方向与温度梯度一致,但方向相反,大小与温度梯度成比例,比例系数为,称为热导率。
解析 B。解析:conduction是热传导,它主要发生在固体中,是通过分子间的碰撞传递热量。convection是热对流,它主要发生在流体(液体和气体)中,是通过流体的流动传递热量。所以主要发生在流体中的是convection,A选项conduction不符合,C选项both错误,D选项neither不对。
