Ocean storms develop when the air temperature in one area is different from the temperature nearby.

T2 So this is an isotherm at some different temperature T2, a cooler temperature, because this was an expansion.

这个绝热过程的温度是,比T1低，因为这是个膨胀过程。

So this is going to end up at T2 a different temperature, we'll call it T2.

这个的末态有不同的温度,我们叫它。

You need a substance and then that substance has to have a property that changes depending on the heat flow, i.e., depending on whether it's sensing that it's the same temperature or different temperature than something else.

你需要某种物质,它的某种性质,随着热量的流动而改变，也就是说,依赖于它是否感觉到它,与其他的物体处于相同的温度。

This is going to end up at a different temperature by the way. You saw this last time in a slightly different way. Last time what you saw is we compared isothermal and adiabatic paths that ended up at the same final pressure, and what you saw is that therefore they ended up in different final volumes.

末态温度是不一样的,上次你们看到的,和这个有一点不一样,上次我们比较的是末态压强,相等的等温过程和绝热过程,因此它们的末态,体积是不一样的。

And if you go back into the 1800's when thermodynamics was starting, there were a zillion different temperatures scales Everybody had their own favorite temperature scale The one that we're most familiar with is the centigrade or Celsius scale where mercury was the substance, and the volume of mercury is the property.

如果你回头看看19世纪温度计,刚开始使用的时候，那时有不计其数的不同温标,每个人都有他们自己最喜欢的温标,我们最熟悉的是,摄氏温标，用水银,作为工作物质，水银的体积是所用的性质。

Now, the coefficient that relates the amount of heat in to the temperature change is obviously going to be different for these two cases.

在这两个例子中,很显然联系热量和温度变化的系数,是不一样的。

This is very different from the functions of state like pressure and temperature.

联系初末两态的整个过程,这与压强。

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。

V They do have the same temperature though.

不同，a，different，volume。,但是温度是一样的。

V2 And there's going to be some volume V2 and some volume V1, but are not necessarily the same. Especially since the pressures are different. we don't know yet about temperature so I don't know what to say about these volumes because I don't know what the temperatures' are going to do.

这里的体积会变成2,这里的容积是V1，它们不必相等,尤其是当压力不相等的时候,我们还不知道温度,所以我不能说这里的容积,是多少因为我不知道,温度会怎样变化。
