It is taking place inside this thing, and it's a constant pressure, and we'll do it reversibly, right. So that's what we've got.

它是绝热的，在这个内反应,是在恒压下，它是可逆的，对吧？

You just change volume to pressure and basically you're looking at enthalpy under a constant -- anything that's done at a constant volume path with energy, there's the same thing happening under constant pressure path for enthalpy.

可以看到这就是把体积换成了压强,一般我们都是在一种恒定状态下,考虑焓的，任何在恒容条件下,能伴随能量变化的东西，也在恒压条件下伴随焓同样地变化,所以你可以经常。

He presents himself, in other words, as a human being of unparalleled piety and devotion who will risk life itself rather than quit the post that has been given to him.

他呈现的自我，换句话说，是极度虔诚敬神的人类,甚至压下自己的生命作赌注,也不愿放弃这个天赐的角色。

We already did that. OK, dH/dT constant pressure is Cp. That was easy one.

我们已经做过这个计算了，好的，在恒压,状态下的偏H偏T就是Cp，这个很简单。

dT That means that dH is also equal to dH/dT, constant pressure dT. All right, so now I've T ot more dH/dT under constant pressure.

也等于偏H偏T恒压乘以，现在我已经得到了在恒压,状态下的偏H偏。

T Remember, we're trying to get delta H, p we're trying to get dH/dT constant pressure and dH/dp constant temperature. OK, these are the two things were trying to get here.

想要得到在恒压状态下的偏H偏，和在恒温状态下的偏H偏,好的，这是两个我们，在这里想要得到的东西。
