09: 1.23 moles of a monatomic ideal gas is used in a heat engine involving three steps: (1) The gas starts at STP and is adiabatically compressed to half its original volume. (2) The gas is expanded, at constant pressure, back to its original volume. (3) The gas is cooled, at constant volume, back to STP. (a) Sketch the cycle on a PV diagram. (b) Determine P, V, and T at the end of the first step.
