How do we go from that experiment to H the terms that we're trying to get, these slopes.

我们怎样从实验得到我们想要的量？,记住，我们想要得到Δ

And so we can actually think about how do we calculate what the dissociation energy should be for h 2, so let's go ahead and do this.

因此，我们其实可以想到应该如何计算,氢分子的离解能，那么我们开始做一下吧。

But how do we get to 1861 and that secession crisis with Alexander H. Stephens delivering this Cornerstone Speech, declaring that, "Hey folks, it's all about slavery and its preservation?"

但事情怎么会演变到1861年那样,乃至之后的分离危机,亚历山大为何能在这篇演讲中,宣称,"嘿,伙计们,今天我要讲的是奴隶制和对其保护"

So in principle, if I measure how much hotter, I can determine how much heat was produced, and from that, I should be able H to calculate delta H at T1.

所以原则上，如果我测量，变热了多少，我就能确定，有多少热被产生,从中我就可以计算T1下的Δ

cs50 h It's not called standard io.h, it's called cs50.h. That's where the code we wrote for you will live and then we'll see how to do this in examples today onward but we wrote for you some tools, some functions that calls GetChar for get a character.

当然不是标准输入输出库了，而是叫做,这里面有一些我们写的代码,等一下我会举几个例子,我们写了一些函数,比如GetChar，意思是得到一个变量。

We're just going to go through it and execute it a little bit. And then we'll move on and talk about how we'd actually make some of these measurements of delta H and compare

对吧？我们会讲完它并,实际应用一下，然后我们会,继续讲一下实际上我们,是怎样测量△H并与

OK, delta H is delta of u plus pV. By definition that's how we define enthalpy up here.

好，ΔH=Δ,根据定义，这就是我们。

And the last thing we can think about is how do we name this n h bond, and again, we just name it based on it symmetry.

最后我们要讨论的是,如何命名这个NH键，同样，我们基于它的对称性命名它。

So how does delta H change if we change the temperature?

对吧？那么如果我们改变温度,ΔH会如何变化？
