We want a relationship in p-V space, not in T-V space. So we're going to have to do something about that. But first, it turns out that now we have this R over Cv.
我们想要p-V空间中的结果,而不是T-V空间中的,因此需要做一些变换,先来看现在的关系,它跟R/Cv有关。
The equation gives a good correlation for vapor pressures of pure solvents as well as P-V-T behaviors of supercritical carbon dioxide.
该方程较好地关联了纯溶剂蒸汽压及超临界二氧化碳的P-V-T关系;
It's true for any gas, and if I remove this limit here, r t is equal to p v bar, I'm going to call that an ideal gas.
这样的气体被称作理想气体,这就是理想气体的性质,理想气体的涵义是什么?
So instead of v bar, we write p v bar minus b, equal r t.
现在考虑,这些气体分子之间。
V So this nR over V. And then, using the relation again, T we can just write this as p over T.
恒定温度下的dp/dT等于nR除以,再次利用状态方程,可以把它写成p除以。
