Were going to make it for a mole of gas, T1 so it's R times T1, V and then we'll have dV over V.
假设是有一摩尔气体，那么就是R乘以，然后有dv除以。

So, what we get for the disassociation energy for a hydrogen atom is 424 kilojoules per mole.
因此，我们就得到了氢原子,离解能的大小为，424，千焦每摩尔。

People can get hung up on sort of hunting these things down, and stamping them out, one at a time. And it's a little bit like playing Whack-a-Mole. Right?
我们可能会一次一个的去发现,这个bug并且消灭它，这有点像打鼹鼠对不对？,不停的有鼹鼠跳起来？
-
So we're going to start with a mole of gas, V at some pressure, some volume, T temperature and some mole so V, doing it per mole, and we're going to do two paths here.
假设有1摩尔气体，具有一点的压强p，体积，温度，我们将让它，经过两条不同的路径。
