the total amount of the work that we can get out is just given by the area inside this curve.

能够输出的功就是,我们可以得出来,曲线所包围的面积。

W2 So in this case, it's the amount of work is the area under that curve. And in this case here, the amount of work is bigger, w2 is bigger and it's the area under this curve.

这是路径2做的功,比W1要大，现在假设,我把这两条路径结合起来。

If it's a reversible process, we know the work is the area under the curve.

对可逆过程，功等于p-V图上。
