The graph shown is for a dilute gas that follows the clockwise path of quasi-static steps: isobaric expansion, isochoric reduction of pressure, isobaric compression, and isochoric increase in pressure. The vertical axis is shown in multiples of the pressure pp, where p=2.5atm, and the horizontal axis is shown in multiples of V, where V=4L.
