另一种可能是下沉的板块冷却了邻近的地幔，并产生对流，使板块移动。

Another possibility is that the sinking plate cools the neighboring mantle and produces convection currents that move the plates.

想像一下吧，这样的环境根本不需要冷却了！

Imagine an environment that does not need cooling at all!

降雨冷却了空气，这就向下产生了气流。

Falling rain cools the air as it descends.

That's the work that the system is doing to the environment. I'm doing work to the environment. The work is negative, which means that work is being done to the environment.

功的大小,就是矩形的面积,这样我们就实现了一台热机，冷却，加热，加热,冷却，系统回到了初态。

So what I'm doing here is I'm cooling, and then when I'm sitting at a fixed volume and I'm increasing the pressure, what am I doing? I'm heating, right?

对了，因此在这里，需要冷却,而在这里，当体积不变增加压强时？
