2 moles of a diatomic ideal gas are taken through a non-cyclic path consisting of
three thermodynamic processes as shown above. The gas starts of point A, then
undergoes an isochoric process to point B. It is then compressed isothermally to
point C. Finally, the gas undergoes an isobaric compression to point D.
