One mole of a diatomic (rigid rotator) ideal gas has an initial volume of 1 L and
temperature of 400 K (state A). First the gas undergoes an isometric process such that
the final pressure is 4 times the initial pressure (state B). It then expands isothermally
back to the initial pressure (state C). Then it is compressed isobarically back to its
original state.
