2) Two kg of axygen fils the cylinder of a piston-cylinder assembly. The initial volume and pressure are 2 m and 1 bar, respectively. Heat transfer to the oxygen occurs at constant pressure until the volume is doubled. Determine the heat transfer for the process, in kJ, assuming the specific heat ratio is constant, k= 1.35. Kinetic and potential energy effects can be ignored AQ= 781.2 kJ BQ- 871.2 kJ CQ= 791.2 kJ D.Q= 771.2 kJ Plam -2kg
