And so, again, we see a temperature increase, and we know the work, and the temperature increase, it's a constant pressure thing.

好，我们看到温度升高了，然后我们有做功量和温度的升高量，这是一个恒定压力下的值。

So I've got, this piston here is compressed, and I slowly, slowly increase the volume, drop the temperature.

这样，这个活塞就被压缩了，然后我再很慢很慢地增加它的体积，降低温度。

And so an experiment said the gas didn't increase its temperature when it expanded the vacuum.

这个实验告诉你,气体在向真空膨胀的过程,中温度没有升高。

Joule actually did this experiment, and he observed that for the gas expansions that he could do, that the temperature did not increase measurably.

事实上焦耳的确做了这个实验，他做到了,他能达到的最好实验要求，发现在可测量范围内没有观察到温度上升。
