It's tabulated in books, and this we can measure p in the experiment. Delta p here is the change in pressure from the left side to the right side, and we can put a thermometer, measure the temperature before the experiment and measure the temperature after the experiment.

这列在书上，这个量我们在,实验中也可以测量，在这里Δ,是从左边到右边的压强变化，我们可以放一个温度计，去测量实验前的温度,再去测量试验后的温度。

Our piston on the right side here fully out, and the piston on my right side, your left side, fully inside. There's no gas p1 on that side here. So there's p2 sitting here.

左边的这个活塞完全在外面，而右边的左边的这个活塞完全在里面，这边没有一点空气,这边是P2，这边是。
