7.5) A 1.15 -mol quantity of monatomic ideal gas undergoes the
following cyclic process. The gas starts at point a at STP. It
expands isothermally to point b, where the volume is 2.2 times its
original volume. Next, heat is removed while keeping the volume
constant and reducing the pressure. Finally, the gas undergoes
adiabatic compression, returning to point a.
