One mole of a monatomic ideal gas is held  at the start  at a  pressure of 11 atm and 1 L. The gas undergoes isothermal expansion to 4 L followed by adiabatic expansion to 6 L.  The gas is then isothermally compressed to 1.70 atm and adiabatically compressed back to 1 L.

A diatomic ideal gas undergoes the exact same four step process as in problem 1A, starting at PointA (400 kPa, 600K, 1 L) A => B Isobaric expansion that triples the volume B => C Isochoric cooling to one-half the pressure C=> D Isobaric contraction to the original volume. D => A Isochoric heating to original pressure Determine the Pressure, Temperature and Volume at the end of each process. Determine the Change in the Internal Energy, Heat Flow and Work Done by the System during each process and for the entire cycle. Sketch a well labeled PV diagram for this cycle. Determine the Thermal Efficiency of this cycle (Work for Cycle/Heat Flow Into the System).

5. If a gas of volume 6000 cm³ and at pressure of 100 kPa is compressed quasi-statically according to PV² = constant until the volume becomes 2000 cm³, determine the final pressure and the work transfer.
