水体往往在白天吸收热量，然后在夜间把这些热量释放出来。

Bodies of water tend to absorb the heat during the day, and then they release the heat at night.

北极大部分地区被冰雪覆盖，具有很强的反射性；如果冰雪融化，裸露的土壤吸收热量，有助于加速变暖。

Most of the Arctic is covered in snow and ice, which are highly reflective; if snow and ice melt, the exposed soil, which absorbs heat, serves to accelerate warming.

它吸收热量。

It sucks in heat.

Is this possible? That's what the first law says it's possible; work is heat, and heat is work, and they're the same thing. You can break even 100% maybe. So let's go back and see what work is.

00%的效率,我们可以从大气中吸收热量，用来驱动我们的汽车,效率也应该能达到。

So the expansion against lower pressure draws less heat from the hot reservoir right.

所以压强较低时的膨胀,从高温热源吸收的热量更少。

OK, so that means heat is being imparted to the system, right, from the surroundings in a manner that compensates exactly the amount of work done.

好，这表示系统,从外界吸热,吸收的热量与系统,对外做功的值相等。
