And so as we add heat here, that was even quieter than last time.

因此我们在这里加热，怎么比刚才还安静啊？

Heat up the library all the time.

要天天泡在图书馆里。

It's not going to be zero this time because we have non zero heat exchange between the system and the environment, right.?

热力学量，但是现在让我们看一下,我们的特殊函数，这次它不会是零,因为系统与外界的热量交换并不是零，对吧？

You're taking the air inside of the pump and you're compressing it. You're doing it so fast that there's not enough time for heat to come out of the gas that's inside the pump towards the walls of the pump.

你把空气吸进气筒里并且压缩它,你的动作很快以至于,没有足够的时间让热量,从气筒里面跑出来,传递到气筒壁上。

There's no change in them, and then we also looked at some at non-state functions, work and heat, and saw that those aren't zero going around a cycle. Of course you can do work in a cyclic process, and heat can be exchanged with the environment at the same time.

它们不会有变化，然后我们研究了,一些非态函数，功和热量，并看到,沿着循环行进一周的话,它们并不是零，当然你可以在,一个循环过程中做功，而同时热量可以在系统,与外界环境之间进行交换。

All right, now what we're going to learn next time and Bob Field is going to teach the lecture next time, is how heat and work are related, and how they're really the same thing, and how they're related through the first law, through energy conservation.

这节课就到这里,下节课将由Bob，Field讲授,我们将学习功与热量的关系，认识到它们在本质上的相同之处，并通过热力学第一定律，亦即能量守恒定律，把它们联系起来。

Last time you heard about work and heat.

上节课我们学习了功和热。

Every time you do the experiment T in equilibrium with the heat bath at T, v2 you'll get the same p2 and V2.

与热库相接触的每次实验中,达到热平衡后的温度都是，压强都是p2，体积都是。
