And for the sake of this class, we're going to consider most gases to be ideal gases. Questions?

有问题吗？好，现在，这一方程建立了,三个状态函数之间的联系：

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。

So we know that we can relate to z effective to the actual energy level of each of those orbitals, and we can do that using this equation here where it's negative z effective squared r h over n squared, we're going to see that again and again.

我们知道我们可以将有效电荷量与,每个轨道的实际能级联系起来，我们可以使用方程去解它,乘以RH除以n的平方,它等于负的有效电荷量的平方,我们将会一次又一次的看到它。

If you want to write a function that describes this line here, it's pressure as a function of volume related to each other with this constant.

如果要写出描述这条等温线的方程,它的压强和体积,就通过常数C相联系起来。
