Oxygen (molar mass 32 kg/kmol) expands reversibly in a cylinder behind a piston at a constant pressure of 3 bar. The volume initially is 0.01 m and finally is 0.03 m; the initial temperature is 17C. Calculate the work input and the heat supplied during the expansion. Assume oxygen to be a perfect gas and take c = 0.917 kJ/kg K.
