All right, next time we're going to talk about a much better scale, which is the ideal gas thermometer and how we get to the Kelvin scale.
好，下次我们,会讲一种好得多的温标，关于理想气体温度计,和开氏温标的导出。
-
All right, so gamma is for ideal gas, 1 is bigger than one.
对理想气体，γ大于。
-
Now going from three to four right, so we have another isothermal process for an ideal gas, so I won't try to make you sing again so soon.
从第三点到第四点，这也是一个理想气体的,恒温过程，这次不用你们集体回答了。
-
The atoms or molecules in the gas don't know that there are other atoms and molecules in the gas, and then you end up with this universal property. All right, so gases that have this universal property, even when the pressure is not zero, those are the ideal gases.
可以忽略,这样就得到了理想气体的性质,在有限压强下,依然能保持这些性质的气体，被称为理想气体，本课中我们把大部分气体，都作为理想气体来处理。
-
is always equal to for an ideal gas? Cv dT right.
对吧？
-
So it's, this is just the integral pdv And it's an ideal gas, isothermal, right.
从一点到二点的,的积分。，from，one，to，two，of，p，dV。,这是理想气体，恒温过程，好的。
-
Right now we told you Joule did all these experiments and he found out that for an ideal gas, that the limit in and ideal gas 0 case was that the eta J was equal to zero.
现在我告诉你们焦耳,做了所有这些实验,他发现对于理想气体,在极限情况下理想气体的ηJ等于。
