ideal gas

基本解釋

It's like the ideal gas law, and one could know that in principle.
有點像理想氣體定律，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(fā)現(xiàn)，你們也會發(fā)現(xiàn),理想氣體的焦耳系數(shù)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(tài)方程的數(shù)據(jù)，或者從狀態(tài)方程模型比如理想氣體方程,范德瓦爾斯方程或者其他狀態(tài)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(guān)系只對理想氣體成立，上節(jié)課我們,用鏈?zhǔn)椒▌t推導(dǎo)出了這一關(guān)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(tài)方程，這狀態(tài)方程不像理想氣體狀態(tài)方程那么簡單。

The last time you saw that for an ideal gas, the energy only cared about the temperature.
上次你們知道了，理想氣體的能量只與溫度有關(guān)。
