Now, the most interesting one for our class the equation of state that's the most interesting, is the Van der Waals equation of state, developed by Mr. Van der Waals in 1873.

由范德瓦尔斯在1873年发展起来,这个方程的美妙之处，在于它只需要两个参数，下面我们来研究一下。

OK, so we're going to see this using a Van der Waal's gas. Let's look at a Van der Waal's gas and see what happens in the Van der Waal's gas. Any questions, first?

好的，我们接下来看看,用范德瓦尔斯气体,让我们看看范德瓦尔斯气体,并且研究它的性质？

Minus p, right? But in fact, if you go back to the van der Waal's equation of state b here's RT over v minus b.

再减去p，对吗，但是实际上，如果你代回范德瓦尔斯气体的状态方程,这里是RT除以摩尔体积减去。
