Adiabatic meaning there's no heat involved, and we're going to see how that differs from the isothermal expansion and compression.

绝热意味着没有热量的传递，我们将看到它,与等温过程的区别。

The boundary is impervious to transfer of heat like a thermos Anything that happens inside of the thermos is an adiabatic change because the thermos has no connection in terms of energy to the outside world.

边界不能传递热量,像热水瓶一样,热水瓶里发生的任何事,都是绝热变化,因为热水瓶与外部世界,没有能量方面的联系。

We're going to find other properties that do care about the history of the system like work, that you put in the system, or heat that you put in the system, or some other variables But you can't use those to define the equilibrium state.

我们还会发现其他一些,与系统的历史有关的性质,比如你对系统做的功，或者你向系统传递的热量，或其他的变量,但你不能用它们,来定义平衡态。

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。

Now, you can have a change of temperature without any heat being involved.

不进行热量传递也可以改变温度,想象有一个热绝缘的盒子。

Adiabatic means that there's no heat transferred between the system and the surrounding.

绝热是指没有热量,在系统和环境间传递。

It means no heat, no work.

这意味着没有热量传递，没有功。
