## Main Question or Discussion Point

Hey all,

In one of my textbooks, there is a passage in the thermodynamics section that states that:

For a closed cycle where the system returns to its initial state, the work done is the area enclosed by the curve (when looking at a Pressure-Volume graph).

Shouldn't the work done by this process be a total of 0 instead???

Thanks in advance.
