OK, now what we'd like to do is be able to calculate any of these quantities in terms of temperature, pressure, volume properties.

现在我们想要做的是能够利用,温度，压强和体积的性质,计算上面的物理量。

I don't need to tell you the volume here, because you've got enough information to calculate the volume.

这里我不需要告诉你体积，因为你已经获得了足够多的信息,来计算体积。

It's now, all we have to do is say we're going to have heat at constant volume.

我们需要做的就是,计算恒定体积下的热量。
