现在让压强趋于,现在测量气体的压强,和摩尔体积。
So, you do this measurement, you measure with the gas, you measure the pressure and the molar volume.
调节温度和混合气体的压强,模拟海平面以上各种高度的大气状态。
They adjust the temperature and pressure of the mix to mimic conditions at various heights above sea level.
如果把气体装进容器里,容器内各处气体的压强,应该是一样的,否则它就不是平衡的。
If I've got a gas in a container, the pressure of the gas has to be the same everywhere in the container, otherwise it's not equilibrium.
In this case here, our property is the value of the pressure times the volume, times the molar volume. That's the property.
或者电阻,对气体来说,它的特性是气体压强。
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。
If I place my container of gas on the table here, and I come back an hour later, the pressure needs to be the same when I come back Otherwise it's not equilibrium.
如果我把装气体的容器放在桌子上,一小时以后我再回来时,气体的压强应该是不变的,否则它就不是平衡的。
