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。
-
Adiabatic means there's no heat transferred in or out of the system.
绝热意味着系统,与化境没有热交换。
-
"When Norman Rockwell originally painted it, the Red Lion Inn was dark because it was only open seasonally in the summer,because it had no heat.

So if I get rid of these arrows, there's no heat flowing because they're in thermal equilibrium, then I can't have an arrow here.
所以如果我擦去这些箭头，没有热流存在,因为它们处于热平衡，那么这里也不能存在一个箭头。
-
But if there's no heat flowing between these two, ac and no heat flowing between these two then you can't haveheat flowingbetween these two.
那么，这两者,也不会有热量流动。
-
If there's no heat flow between the b and c, then I can say all right, a and c were the same temperature.
如果在与之间没有热量流动，那么我就可以说，好吧与处于相同的温度。
-
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。
-
There's no heat flowing from the environment to the system. I have to define my terms.
系统与外界间,并没有热传递发生。
-
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。
-
There's no heat that can go through the walls of the thermos.
没有热量能,穿过热水瓶的瓶壁。
-
Since it's isolated, no heat is added.
因为它是与环境隔绝的，因此没有热量交换。
-
This is isothermal. This is adiabatic, there's no heat.
一个是等温，一个是绝热。
-
It means no heat, no work.
这意味着没有热量传递，没有功。
-
This is providing work that's being used in here, but if you take the whole outside of the surroundings and this whole thing is the system, no net work, these things cancel each other, and yet heat's going up.
如果把外面的全部当成环境，把这里的全部当成系统,那么就没有净的功，它们相互抵消了，热量向上传输，会发生什么？
-
Let's say there's no heat flow.
让我们假设没有热量流动。
-
U It's u, because u is to q plus w right, heat and work, but it's adiabatic. So there's no heat, exchange with the environment, and it's constant volume, so there's no p dV work, right.
什么是零？是U，因为,等于q加w，热量和功，但这是绝热的，所以系统与环境间没有热量交换；,同时它是灯体的，所以也没有pdV形式的功。
