Sketch a PV diagram and find the work done by the gas during the following stages. (Draw the PV diagram on paper. Your instructor may ask you to turn in this work.)
(a) A gas is expanded from a volume of 1.0 L to 2.6 L at a constant pressure of 3.3 atm.
(b) The gas is then cooled at constant volume until the pressure falls to 2.2 atm.
(c) The gas is then compressed at a constant pressure of 2.2 atm from a volume of 2.6 L to 1.0 L.
(Note: Be careful of signs.)
(d) The gas is heated until its pressure increases from 2.2 atm to 3.3 atm at a constant volume.
(e) Find the net work done during the complete cycle.
