For a real gas it depends on more than the temperature STUDENT: Are there any other constraints similar to that .

而对实际气体，这是不对的,它的内能不仅仅依赖于温度,学生：有其他,类似的约束吗？

You've got to put more pressure on one side than the other if you want to push that gas through the throttle, right? So this is where the time scale issue comes into play.

如果你想让更多的气体通过节流阀,应该使一边的压强,大于另一边，是吗？所以这就是,时间尺度发挥作用的地方。

As I say, red tends to be chosen, but then if you get lab experiments showing that that particular color of gas blue is somehow or another sort of more invasive of your consciousness than red is, then you move away from the arbitrariness of the choice of red as a color.

所以人们就倾向于选择红灯，但是如果你想用实验证明,比如说烟蓝色或者,其他任何另一种颜色比红色更加醒目，那么你就忽视了颜色选择上的任意性。

Higher entropy basically because you're forming molecules of gas where there weren't any before, and there's more disorder in the gas phase than in the liquid. That is, the gas phase molecules have more freedom to roam.

高的熵是因为,我们产生了以前不存在的气体分子,气体的无序程度比液体大，换句话说,气相的分子，有更多的到处游荡的自由度。

And it's more dramatic if the system is a gas p T2 V2 p, T2, V2, And let's look at what happens to U these functions of state, to H to u under this transformation.

如果是气体这个系统,就更具有趣了,让我们看看H和，在这个变化中态函数会发生什么变化。
