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 2.5 L at a constant pressure of 2.8 atm.
J
(b) The gas is then cooled at constant volume until the pressure falls to 1.9 atm.
(c) The gas is then compressed at a constant pressure of 1.9 atm from a volume of 2.5 L to 1.0 L. (Note: Be careful of signs.)
(d) The gas is heated until its pressure increases from 1.9 atm to 2.8 atm at a constant volume.
(e) Find the net work done during the complete cycle.
