ideal gas

基本解释

It's like the ideal gas law, and one could know that in principle.
有点像理想气体定律，我们可以从原理上理解这点。
And we saw that, you saw that the Joule coefficient for an ideal gas was zero.
我们会发现，你们也会发现,理想气体的焦耳系数是零。
So from measured equation of state data, or from a model like the ideal gas or the van der Waal's gas or another equation of state you know this.
所以，从测量的到的状态方程的数据，或者从状态方程模型比如理想气体方程,范德瓦尔斯方程或者其他状态方程,我们就可以知道。

OK, this is only true for an ideal gas, and we went through that mathematically where the, with a chain rule.
这一关系只对理想气体成立，上节课我们,用链式法则推导出了这一关系。

Let's try it with a different equation of state, that isn't quite as simple as the ideal gas case.
考虑一个不同的状态方程，这状态方程不像理想气体状态方程那么简单。

The last time you saw that for an ideal gas, the energy only cared about the temperature.
上次你们知道了，理想气体的能量只与温度有关。
