Now, we saw before, or really I should say we accepted before, that for an ideal gas, u was a function of temperature only.
我们已经看到,或者说我们已经接受这样一个事实,即理想气体的内能只和温度有关。

This graph shows some of it as well, but in this case for children, in the left hand side you see the ideal composition of the diet according to government recommendations that the diet should be partitioned in this way.
这个图表也揭示了一些类似的事实,不过是在儿童饮食中的情况,在左边你看到的是理想的饮食组合,按照政府的推荐食谱,食物应该这样搭配
That for an ideal gas it has to be the case that there's no volume dependence of the energy.
我们可以直接推导这个结果,即证明对理想气体,内能和气体体积无关。
You're allowed Cv comes out here for this adiabatic expansion, which is not a constant volume only because this is always true for an ideal gas.
绝热过程写下,这个式子是因为它对理想气体都成立,并没有用到等容过程的条件,只用了理想气体的条件。
This quantity is exactly zero for an ideal gas and we'll discover why eventually it has to do with what we mean by an ideal gas it turns out.
对理想气体它是零,这点我们接下来会知道是,为什么,这与为什么我们叫它理想气体有关。
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。
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。
In other words, we're taking advantage of the fact that we now know that quantity. In the case of the ideal gas we just have a simple model for it.
换句话说,我们可以利用我们已经,了解这个物理量的这个优势,对理想气体我们有一个简单的模型。
And we saw that, you saw that the Joule coefficient for an ideal gas was zero.
我们会发现,你们也会发现,理想气体的焦耳系数是零。
du=0 Delta u sub 3 is, for an ideal gas.
就是。
I gotta put that constraint in there for an ideal gas.
注意只适用。
For gases that approach ideal gas conditions.
现在你能看到这样的结果。
but right now you're going to have to take it for granted. So, if the Joule-Thomson coefficient is equal to zero, just like we wrote, du = Cv dT du = Cv dT for an ideal gas, we're going to dH = Cp dT have dH = Cp dT for an ideal gas as well.
但是现在请你们应该把它看成理所当然的,所以,如果焦耳-汤姆逊系数等于零,就像我们写的,对于理想气体,我们也可以得到对于理想气体。
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。
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 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:
And now we're going to specify, we're going to do a Carnot cycle for an ideal gas.
我们具体地指定一个卡诺循环,这是理想气体。
So for an ideal gas then, dH/dp under 0 constant temperature, that has to be equal to zero.
所以对于理想气体,偏H偏p在恒温下,等于。
But this is only true for an ideal gas and it's approximately true for other things.
但这只对,理想气体城里。
All right, so gamma is for ideal gas, 1 is bigger than one.
对理想气体,γ大于。
