That's the some of delta u in these two paths and if we look at delta u in just path A, it's zero.

这是这两条路径△U的和,如果我们要看路径A的△U，它也是零。

Adiabatic q equal to zero. It's also delta H 0 which is zero. The two didn't necessarily follow because remember, delta H is dq so p is only true for a reversible constant pressure process.

在这个过程中ΔH等于,绝热的所以q等于0，而ΔH也等于,这两个也不一定有因果关系,因为，记住，ΔH等于dq只有在恒压。
