They named their albums "Volume One" and "Volume Two" for the same reason.

These two relations involving entropy are also useful because they'll let us see how entropy depends on volume and pressure.

这两个涉及熵的关系也非常有用,因为他们告诉我们,熵和体积，压强的关系。

But now, what happens if, instead we look at what happens when we go to some state one to some other state two and it's the pressure. Or the volume, that changes.

但是现在，我们看看如果,我们关系从状态一变化到状态二时,体积或者压强发生变化。

They recently released a second album called "Volume Two."

In this case, V = /P. Have two quantities and the number of moles gives you another property. You don't need to know the volume. All you need to know is the pressure and temperature and the number of moles to get the volume.

以及气体的摩尔数,就可以得到第三个量,知道压强，温度和气体的,摩尔数就可以推导出气体的体积,这称为状态方程,它建立了状态函数之间的联系。

And then V minus the excluded volume term is equal to RT. Two parameters, this is the attraction between two atoms or molecules in the gas phase.

以及V减去一个排斥项,等于RT，两个参数，这是气体状态下两个原子,或者分子之间的吸引力。
