5.12 A long vertical cylinder of 100 mm bore, open at the top, contains 0.005 kg of allowed to settle to an equilibrium position. Heat energy is then supplied and the pistorn atmospheric air at 15°C. A close-fitting piston of mass 15 kg is placed in the cylinder and rises 300 mm. If friction is negligible, determine: (a) the absolute pressure of the air in the cylinder; (b) the heat energy supplied; (e) the change in internal energy of the air inside the cylinder (d) the work done by the air in the cylinder (a) 120 kPa (d) +283 J (b) 990 J (c) 708 J
