Three moles of an ideal gas(Cp=7R/2) at pressure P and temperature T is isothermally expanded to twice its initial volume. It is then compressed at constant pressure to its original volume. Finally gas is heated at constant volume to its original pressure P. (a) Sketch P-V and P-T diagram for the complete process (b) CAlculate the net work done by the gas and net heat supplied to the gas during the complete process
