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。
I know I only need 2, so I can relate dV dV to dp through the ideal gas law.
我只需要两个就够了,因此可以用,理想气体状态方程消去。
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。
OK, you use the ideal gas law, etc., then you get a relationship that connects the pressure and the temperature, like here we got a relationship that connected the temperatures and the volumes together.
我们会得到,一个联系初末态,的压强和温度的,关系式,就像这个联系过程中。
It's like the ideal gas law, and one could know that in principle.
有点像理想气体定律,我们可以从原理上理解这点。
let's use the ideal gas law to get rid of the temperature.
我们用理想气体定律,来消去温度。
I'll replace the ideal gas law for those two T's.
用理想气体定律代进去。
Now, if you're an engineer, and you use the ideal gas law to design a chemical plant or a boiler or an electrical plant, you know, a steam plant, you're going to be in big trouble.
比如说锅炉,蒸汽机,我们会遇到一个大问题:,我们设计的机器将无法运作,因为对大部分实际气体。
That's the ideal gas law.
是怎么推导出来的。
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。
