We control how we use time, we control the temperature in the environment, and hermetically seal ourselves in things.

我们控制时间的利用，我们控制周边环境的温度,我们把自己封闭在各种事务中，与世隔绝。

OK, you use the ideal gas law, etc., then you get a relationship that connects the pressure and the temperature, like here we got a relationship that connected the temperatures and the volumes together.

我们会得到，一个联系初末态,的压强和温度的，关系式,就像这个联系过程中。

v du/dV under constant temperature. du/dT v under constant volume. You use the Joule expansion to find these quantities.

像偏u偏v，恒温下的偏u偏,恒容下的偏u偏,你们知道怎么运用焦耳定律。

If I look at different points in my container during that path, I'm going to have to use a different value of pressure or different value of temperature That's not an equilibrium state, and that process turns out then to be an irreversible process.

如果我要研究在路径中容器里的,不同的点，我就得在容器里不同的点上使用,不同的压强值,或不同的温度值,实际上这不是个平衡态，这个过程是,不可逆过程。

What we're really going to do in practice is we're going to measure, we're going to use our thermometer and say great, how much did the temperature change, right.

H1是零,实际上我们要做的,是用我们的温度计,测量温度改变了多少。
