2 moles of an ideal gas is allowed to expand from 0.002 m^3 to 0.02 m^3 while the pressure is held at 325000 pascals. This is done by adding heat to it so tht its temperature rises; at the point, its volume is held constant, and heat is removed so that the pressure drops. The system then returns to its original pressure through the isothermal process. Draw the P-V diagram for this heat cycle. Determine the total work done on or by the gas. Determine the net heat flow in or out of the system.
