What the philosopher tries to do, then, so as to better focus on these ideal things, is to disregard the body, put it aside, separate his mind as much as possible from it.

所以 哲学家们,为了全神贯注于这些理想事物,就要忽略肉体,撇开肉体,尽可能地分离精神和肉体

You've got to squeeze absolutely everything out of it, and so it was ideal from the standpoint of teaching and was, it seems to me, also wonderfully galvanizing intellectually because it really did make people think: "look how intricate what I thought was simple turns out to be."

你得完完全全把东西都挤干净了，正因如此，从教学本身的立场来看，这就是理想状态了，而在我看来，它能使人如醍醐灌顶,因为它真的在引导人们思考：,“我想象得很复杂的东西原来是这么简单的一回事儿啊！“

So that you could see that for the ideal gas, u would not be a function of volume, but only of temperature.

所以我们可以看到对理想气体，内能不依赖于体积，而仅仅是温度的函数。

麻省理工公开课 - 热力学与动力学课程节选

So for an ideal gas, we saw that u was only a function of temperature.

对于理想气体，我们知道内能只是温度的函数。

麻省理工公开课 - 热力学与动力学课程节选

And so that means that delta u is always calculable from Cv dT for any ideal gas change.

这意味着对理想气体,Δu只需利用Cv，dT计算。

麻省理工公开课 - 热力学与动力学课程节选

So what happens then we're going to use the ideal gas law. So it's approximately delta u plus delta nRT. That's a constant. That's a constant.

我们现在要应用理想气体物态方程,这个近似等于ΔU加上Δ,这是常数，这是常数。

They want to get as far away from each other possible, the ideal angle is 120. But what we have here is a four-membered ring, so what angle does 90° that have to be, that bond? 90 degrees.

它们想要尽量远离彼此，最理想的是形成120°键角,但现在是个四元环,所以这键角应该多大？

So this is a very small number and for ideal gases, eta J is equal to zero.

这是一个，很小的数。

麻省理工公开课 - 热力学与动力学课程节选

So from measured equation of state data, or from a model like the ideal gas or the van der Waal's gas or another equation of state you know this.

所以，从测量的到的状态方程的数据，或者从状态方程模型比如理想气体方程,范德瓦尔斯方程或者其他状态方程,我们就可以知道。

麻省理工公开课 - 热力学与动力学课程节选

Now going from three to four right, so we have another isothermal process for an ideal gas, so I won't try to make you sing again so soon.

从第三点到第四点，这也是一个理想气体的,恒温过程，这次不用你们集体回答了。

麻省理工公开课 - 热力学与动力学课程节选

So again, if you do a calculation where you're close enough to the ideal gas and you need to design your, if you have an engineer designing something that's got a bunch of gases around, this is a useful thing to use.

要研究近似理想气体的表现时,这个方程非常有用,下面再来看一个，对我们来说最有意思的,实际气体状态方程：,范德瓦尔斯方程。

麻省理工公开课 - 热力学与动力学课程节选

The atoms or molecules in the gas don't know that there are other atoms and molecules in the gas, and then you end up with this universal property. All right, so gases that have this universal property, even when the pressure is not zero, those are the ideal gases.

可以忽略,这样就得到了理想气体的性质,在有限压强下,依然能保持这些性质的气体，被称为理想气体，本课中我们把大部分气体，都作为理想气体来处理。

麻省理工公开课 - 热力学与动力学课程节选

So enthalpy, for an ideal gas, only cares about temperature.

只和温度有关，压力已经与不重要了，所以这里与p无关。

麻省理工公开课 - 热力学与动力学课程节选

PROFESSOR BAWENDI: So, for an ideal gas, the isothermal is the easy one because the energy doesn't change.

对理想气体，等温过程最简单,因为能量不变。

And so because of that, he's got a better handle on these ideal forms.

正因为如此,他更好地理解了这些理想型相

耶鲁公开课 - 死亡课程节选

We don't have the ideal world that I just described, but to some extent we do, so we want to think about diversifying in this world.

现实世界并不像我刚才说的那么理想，但在某种程度上这种现象还是存在的,所以同样也要考虑多元化的问题。

Great. So now we have this ideal gas thermometer, and out of this ideal gas thermometer, also comes out the ideal gas law.

好，现在我们有了理想气体温度计,由此还可以引出理想气体定律，我们可以得到这条，插值出的直线的斜率。

麻省理工公开课 - 热力学与动力学课程节选

So for an ideal gas then, dH/dp under 0 constant temperature, that has to be equal to zero.
