The goal was to reach a legally binding agreement to reduce greenhouse gas emissions, blamed for heating up the atmosphere.

Your plant is going to blow up, because the ideal gas law works only in very small range of pressures and temperatures for most gases.

理想气体定律,只在一个很小的压强,与温度的范围内适用。

And that will end up winning out at basically any realistic temperature where the stuff really is a gas.

在体系仍然处于气体状态的温度下,熵战胜了能量。

See, up until now I have been talking about gas phase, single atoms, all this stuff.

看，只到现在我们已经讨论了气相，单原子，这些东西。

And the temperature scale that turns out to be well-defined and ends up giving us the concept of an absolute zero is the ideal gas thermometer.

比如理想气体温标,它有精确的定义,并能引出绝对零度的概念,今天我们就先来谈谈它。

So the work that you're doing to expand, to go through this experiment, ends up cooling the gas.

因此在膨胀气体的过程中,气体降温。

"Whatever they did,didn't' work." Stogel says he picked up his recalled 2009 Camry from a dealer after getting repairs to fix a sticky gas pedal.

The atoms or molecules in the gas don't know that there are other atoms and molecules in the gas, and then you end up with this universal property. All right, so gases that have this universal property, even when the pressure is not zero, those are the ideal gases.

可以忽略,这样就得到了理想气体的性质,在有限压强下,依然能保持这些性质的气体，被称为理想气体，本课中我们把大部分气体，都作为理想气体来处理。

The main goals of the summit are to agree on targets to cut to greenhouse-gas emissions and to set up a mechanism to provide developing countries with the billions of dollars needed to cope with climate change.

There's an interplay between the energy inside the gas which is the heat energy which is allowing me to do all that work to be outside, and so I'm using up some of the energy that's inside the gas to do the work on the outside.

即使没有热传递,能量也能以,做功的形式传递出去，气体的一部分内能,转化成了功。

The goal is to come up with substantive, but workable solutions to cut greenhouse gas emissions,promote new, eco-friendly technologies, but also promote economic growth and investment and help the less developed nations to adapt to these new conditions.

That's going to be your heating up of the gas.

这样气体的温度将会升高。
