No matter where you work, somebody is going to be too cold and somebody else is going to be too hot.
不管你在哪里工作,一些人会觉得太冷,一些人会觉得太热。
You know the heat isn't going to flow from a cold body to a hot body without putting some work in to make that happen.
大家知道热量不会自发地,从冷的物理流动到热的物理,除非对它做功。
This can be turned into work by letting it fall down the staircase once again—an analogy of using the movement of hot and cold gases to do work in Maxwell’s original thought experiment.
如果小球再次滚落楼梯的话,其势能就能转化为功,类似于麦克斯韦在最初的头脑试验中使用冷热气体的运动做功一样。
And we had the similar statement by Kelvin about the heat engine that required that some heat gets dumped into a cold reservoir in the process of converting the heat from the hot reservoir into work.
相同的陈述,同样的有开尔文表述:,把热量完全从高温热源,转移至低温热源的过程中,必然有功的输出。
You know the heat isn't going to flow from a cold body to a hot body without putting some work in to make that happen.
大家知道热量不会自发地,从冷的物理流动到热的物理,除非对它做功。
