So, zeroth law, then, allows you to define the concept of temperature and the measurement of temperature through a thermometer.

因此第零定律，使你可以定义温度的概念,以及通过温度计,测量温度的方法。

Now, I know how to relate the heat flow to temperature change, through the heat capacity.

现在我知道怎样把能量的流动,和温度的变化联系起来，通过热容。

When they separate, the primers that you've added automatically bind through the process of hybridization, and then you turn up the temperature to the optimum for Taq polymerase and DNA synthesis starts.

当双链解旋后,加入的引物就会在杂交的步骤中自动,和解旋后的DNA结合,然后你再将温度升高至,Taq酶的最适温度,DNA就开始合成了

Now let's change the pressure and temperature and sweep through a whole range of pressures and temperatures and measure the volume in every one of them.

然后改变气压和温度,并且让气压和温度,取便所有可能的数值,测量相应的体积。

Similarly for G as a function of temperature and pressure, I can go through the same procedure.

同样的G作为,温度和压强的函数，我可以采用相同的步骤。

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。

But you don't compress it so quickly that you're not in there reversible process so you compress that if you were to feel the temperature of the air and you can feel it through the nozzle gives you an idea of the temperature of the air inside your bicycle pump.

但是压缩速度,也不能太快,否则就不是,可逆过程了,这样当压缩气体时,从喷嘴可以感受到,内部气体的温度。

Or in many kinds of gas refrigerators where you push a gas through a nozzle close to room temperature, what you find is that the gas coming out on the other side under lower pressure is cooler than the gas that went through on the other side.

或者在很多种压缩气体式冰箱中,你让气体通过接近室温的管口,你会发现从压力低的一边,出来的气体比通过,另一边的气体更冷,真正的冰箱实际上通过。
