Oxygen (molar mass 32 kg/kmol ) expands reversibly in a cylinder behind a piston at a constant pressure of 3.196 bar. The volume initially is 0.0117 m3 and finally is 0.0314 m3; the initial temperature is 17.56 0C. Calculate the heat supplied during the expansion in the correct unit to two decimal places. Assume oxygen to be a perfect gas and take the specific heat at constant pressure as = 0.917 k J / k g K and molar gas constant as = 8,314 J / kmol K
