Sketch a PV diagram and find the work done by the gas during the following stages. (a) A gas is expanded from a volume of 1.0 L to 5.5 L at a constant pressure of 5.5 atm. (J) (b) The gas is then cooled at constant volume until the pressure falls to 1.5 atm. (J) (c) The gas is then compressed at a constant pressure of 1.5 atm from a volume of 5.5 L to 1.0 L. (Note: Be careful of signs.) (J) (d) The gas is heated until its pressure increases from 1.5 atm to 5.5 atm at a constant volume. (J) (e) Find the net work done during the complete cycle. (J)
