The amount of work you've put in to get here depends on the path. It's not a function of state.

这些量就能,决定系统的状态了。

The reason for inexact doesn't mean it's a crummy measurement, t means that it's path dependent, and so the value of this integral depends on how you get from one to two.

这是因为它是,与积分路径有关的，因此这里的积分值，取决于从一端到二端的,具体路径。

This depends on the path. It tells you right here the path is constant pressure. These don't depend on the path, right. V doesn't care how you v get there. u doesn't care how you get there.

这由变化的具体路径决定,这个小脚标表明过程是恒压的,这些量都与具体路径无关,即不管是通过什么路径使得体积变化为Δ
