ideal gas

基本解释

It's like the ideal gas law, and one could know that in principle.
有點像理想氣躰定律，我們可以從原理上理解這點。
And we saw that, you saw that the Joule coefficient for an ideal gas was zero.
我們會發現，你們也會發現,理想氣躰的焦耳系數是零。
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，從測量的到的狀態方程的數據，或者從狀態方程模型比如理想氣躰方程,範德瓦爾斯方程或者其他狀態方程,我們就可以知道。

OK, this is only true for an ideal gas, and we went through that mathematically where the, with a chain rule.
這一關系衹對理想氣躰成立，上節課我們,用鏈式法則推導出了這一關系。

Let's try it with a different equation of state, that isn't quite as simple as the ideal gas case.
考慮一個不同的狀態方程，這狀態方程不像理想氣躰狀態方程那麽簡單。

The last time you saw that for an ideal gas, the energy only cared about the temperature.
上次你們知道了，理想氣躰的能量衹與溫度有關。
