If you start segregating the gases, there are fewer possible configurations that because you're forcing a particular set of circumstances.
如果你开始分离这些气体，整个系统所具有的可能的状态就会变少,你强加了一个特定的条件。
-
is actually looking at how to regulate greenhouse gases under existing environmental laws,
其职务是研究在现行的环境法下如何管理温室气体的排放，
-
OK, for most gases, T inversion is much 300K greater than 300 degrees Kelvin. Much greater than room temperature.
好，对大多数气体,转变温度都高于,比室温高很多。
-
I left out the noble gases here because they do something a little bit special, and actually, I'm going to give you one last clicker question today to see if you can tell me what you think noble gases do.
我并没有把稀有气体算在里面,因为它们的电子亲和能有点特别，实际上，我将会把这作为今天的,最后一个选择题，来请大家告诉我,你们觉得稀有气体电子亲和能应该是怎样的。
-
We have elements that are totally inert, and we have examples of this, the noble gases, dominantly inert.
因为那些元素都是惰性的，而且我们可以举出些例子，比如惰性气体，完全是惰性的。
-
I say this now with great confidence but ten years ago this story, which all the Greeks agreed too, agreed upon in every respect, that the temple of Apollo was built right on top of this, and underneath the floor of the temple was this little room where the gases came up, where the priestess sat, where all of this came up.
我现在敢在这里夸夸其谈,但是十年前,当时的希腊人,对这个传说都是深信不移的,阿波罗神庙正好建在它上面,神庙地板底下正是气体出现的小屋,女祭司也坐在这里,一切都发生于此
-
The reason the entropy of the mixed gases is the highest is because that has the most possible configurations.
因为混合气体具有最多可能的状态,所以混合气体的熵最大。
-
And typically, we'll be treating at least some cases where we're dealing with ideal gases in which case we can easily get delta u.
那么我们也可以定出功，对吧？,典型地，我们至少会处理,一些理想气体的情况。
-
This needs to be stressed that this is the ideal gas case. Now regular gases, real gases fortunately as I said, don't obey this.
需要强调的是这是对理想气体而言的,普通气体，真实气体，就像我说过的,不遵循这个规律，这是非常重要的。
-
Your plant is going to blow up, because the ideal gas law works only in very small range of pressures and temperatures for most gases.
理想气体定律,只在一个很小的压强,与温度的范围内适用。
-
Real refrigerators actually work with liquids that go into gases so use the latent heat of the liquid, so it doesn't really work like the Joule-Thomson expansion. So this is real.
液体变成气体来工作,以运用液体的潜热，所以这不是,真正像焦耳-汤姆逊膨胀一样工作,这是真实的气体，不像焦耳。
-
And for the sake of this class, we're going to consider most gases to be ideal gases. Questions?
有问题吗？好，现在，这一方程建立了,三个状态函数之间的联系：
-
Versus looking at, for example, helium or neon or argon, these are all inert gases, inert meaning essentially do not react, those were grouped together in the periodic table.
相反，他发现氦，氖，氩，都是惰性气体，惰性的意思是基本不参与化学反应，因此把它们放在周期表中的同一类里。
-
Yes, and if we have gases involved, it's pretty similar, but now what will have is something like this. We'll have a reaction vessel that's sealed, it's constant volume.
如果涉及了气体，情况也很相似，只是现在的装置是这样的,我们有一个密封的反应容器,它的体积是恒定的。
-
when we remove the barrier and the gases mix, you know it's over.
当我们移走隔板并且气体混合后，我们知道事情就结束了。
-
Well, the equilibrium state is the one with the gases completely mixed.
平衡态就是,气体完全混合的态。
