This piston is being brought out, so we expect 0 the work to be negative, negative. And we start o V2 ut with zero volume. We end up with a volume p2 of V2, and the external pressure is constant to p2.
On a big up day like we had today, you would expectvolume to be well, well, well above average, not just like 8% on the Nasdaq and then flat on the NYSE.
