Sketch a PV diagram and find the work done bythe gas during the following stages.
(a) A gas is expanded from a volume of 1.0 L to 8.0 Lat a constant pressure of 8.0 atm. J(b) The gas is then cooled at constant volume until the pressurefalls to 1.5 atm. J(c) The gas is then compressed at a constant pressureof 1.5 atm from a volume of 8.0 L to 1.0 L.(Note: Be careful of signs.) J(d) The gas is heated until its pressure increasesfrom 1.5 atm to 8.0 atm at a constantvolume. J(e) Find the net work done during the complete cycle. J
