热量
定义
热量(heat)是指物体内部的分子运动所具有的能量,是一种能够传递的能量形式。热量的单位是焦耳(J)。
例句
- The temperature of the water rose as heat was applied.(随着热量的加入,水的温度上升了。)
- The metal bar conducts heat well.(这根金属棒良好地传导热量。)
用法
热量通常用于描述能够传递的能量形式,例如加热物体或者进行热能转换。可以用于描述物质的状态变化,例如融化或者沸腾。
近义词
thermal energy, heat energy
反义词
cool
对流
定义
对流(convection)是指流体(气体或液体)由于温度差异而产生的运动。热空气或热水会上升,冷空气或冷水会下沉,形成对流。对流可以有效地传递热量。
例句
- The heat from the radiator caused convection currents in the room.(暖气片散发的热量在房间内形成了对流气流。)
- Convection is the primary way that heat is transferred in the Earth's atmosphere.(对流是地球大气中热量传递的主要方式。)
用法
对流通常用于描述流体中的运动,例如大气中的温度差异导致的气流或者液体中的富含热量的流体上升和富含冷量的流体下沉。对流还可以用于描述热量的传递方式。
