Air is compressed from an initial state of 1 bar and 298.15K toa final state of 5 bar and 295.15K by three different mechanicallyreversible processes in a closed system: • Heating at constantvolume followed by cooling at constant pressure • Isothermalcompression • Adiabatic compression followed by cooling at constantvolume Show these processes in a PV diagram and calculate the workrequired, heat transferred, and the changes in internal energy andenthalpy of the air for each process. For air, Cv ig = 20.785 andCp ig = 29.100 J/mol/K
