Parts of it may be even at zero bar, if I go really fast.

如果我动作太快，某些部分甚至会是零巴。

That little zero, that little superscript means one bar always. OK.

这个小上标的意思,是处于1巴气压下。

pV=RT p plus a over v bar squared times v bar minus b equals r t. All right if you take a equal to zero, these are the two parameters, a and b. If you take those two equal to zero you have p v is equal to r t.

我们就回到,也就是理想气体,状态方程,下面我们来看看,这个方程。

As p goes to zero of p times v bar.

适用于任何气体。

And so now we have this quantity, p times v bar, and the limit of p goes to zero is equal to a constant times the temperature.

不仅仅对氢气或氮气适用，在p趋于0的极限下,它适用于任何气体。
