好,下次我们,会讲一种好得多的温标,关于理想气体温度计,和开氏温标的导出。
All right, next time we're going to talk about a much better scale, which is the ideal gas thermometer and how we get to the Kelvin scale.
取而代之的作法是用理想气体温度计精确地测量分布于较宽温度范围内的几个定点的温度值。
What is done instead is to use the ideal-gas thermometer to determine accurate values for several fixed points that cover a wide temperature range.
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。
Great. So now we have this ideal gas thermometer, and out of this ideal gas thermometer, also comes out the ideal gas law.
The last time you saw that for an ideal gas, the energy only cared about the temperature.
上次你们知道了,理想气体的能量只与温度有关。
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。
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。
