Sulphur dioxide is circulated as refrigerant in a small refrigerator. SO2 gas at a pressure of 5 bar and temperature 340 K is to be cooled at a constant volume of 0.142 m3, to 293 K as part of the refrigeration cycle. Calculate (a) The heat liberated, (b) The work done by the gas on cooling, (c) The final pressure attained on cooling and (d) The change in enthalpy. Sulphur dioxide may be treated as an ideal gas. The specific heat (J/mol K) is found to vary with temperature (K) according to Cp = 25.736 + 5.796 X 10-2 T – 3.8112 x 10-5 T2 + 8.612 x 10-9 T3
