4. Two moles of a monatomic ideal gas are taken through a three process thermodynamic cycle. The gas starts with a pressure PA = 16 atm and a volume VA = 1 L. The gas is then expanded adiabatically to point B. The temperature at point B is TB = 25 K. The gas is then compressed isobarically to point C where the volume is equal to VA. The gas is finally returned to state A via a constant volume process. For L* atm all calculations using the ideal gas law assume that R=0.08- For any mol * K calculations of work, heat, internal energy, or entropy use R = 8.0- J mol* K a. Find all unknown temperatures, pressures, and volumes. Organize all of your data into a table. b. Draw a PV diagram for the thermodynamic cycle described. c. Find the work done by the gas going from A to B. d. Find the change in entropy of the gas going from C to A. e. Find the change in heat for the gas going from B to C.
