He said it would be best to let the people themselves decide if New Mexico would be a slave or free state.

But it is interesting. Let's just, for an order of magnitude say what happens for ground state electron in atomic hydrogen?
但行星模型其实挺有趣的,按照重要的先后顺序,我们来猜想一下,氢原子中的基态电子会发生些什么?
Let's try it with a different equation of state, that isn't quite as simple as the ideal gas case.
考虑一个不同的状态方程,这状态方程不像理想气体状态方程那么简单。
The polis is not merely a city state in the same way as,let us say, the Mesopotamian city states of the third millennium B.C. Were.
那就是城邦不仅仅是一座城市,并不是像,我们说的公元前三千年的,美索不达米亚的城市
OK, so now let's try to formulate how to describe the equilibrium state and what dictates spontaneity.
现在我们尝试,找出如何描述平衡态以及,什么东西表明自发性。
So let's take our one model that we keep going back to Equation of state, and just see how it works.
我们回到经常使用的理想气体模型,或者说状态方程。
And the equation of state, pressure versus volume at constant temperature, is going to have some form, let's just draw it in there like that.
系统的态函数,恒温下压强比体积,变化曲线,就像这样。
This is going to be probably a homework at some point to do this. For now, let's take it for granted. Let's take it for granted that we know how to calculate this derivative from an equation of state like this.
这可能是将来的一个课后作业,现在,请把这当成理所当然的,理所当然地认为我们,知道怎样从一个状态,方程计算这样的微分式。
So let's just state that.
我们说。
State one goes to state two. Let's have constant T.
在恒定的温度下。
The initial state, let's look at what we are doing.
初始状态,这就是我们要了解的。
b Let me just first write it down, the Van der Waals equation of state.
有两个参数,a和,如果a和b等于0的话。
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。
