But now, so this is where the refrigeration comes in. So if you take a gas, and you're below the inversion temperature and you make it go through this irreversible process, the gas comes out colder from that side than that side.

这就是冰箱的原理,如果在低于转变温度,的情况下我们将气体经过,这个不可逆过程,气体出来的温度将比这边低。

Now if you're at the temperature which is b higher than the inversion temperature, in that case here, a over RT is small compared to b, and this is going to turn out to be negative.

T>Tinv】,这时a/bR小于,结果是负数，因此如果温度。

OK, for most gases, T inversion is much 300K greater than 300 degrees Kelvin. Much greater than room temperature.

好，对大多数气体,转变温度都高于,比室温高很多。
