So w, the work is less for the irreversible process than the reversible process.

不可逆过程中系统对外界,做的功要比可逆过程时小。

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。
