Not quite. The work done by an expanding gas is pressure as a function of volume, integrated over volume.

w = ∫p(v)d
fine then, area under the curve, which I mentioned previously. if you get what I am saying, why bring calculus into it?
Thanks for trying to explain it to RDW though.

This can be parameterized using time t, but the pressure-time curve by itself doesn't tell the story.

60 percent of the time, it works every time
