An insulated piston - cylinder device initially contains 0.01 m3 of saturated liquid-vapor mixture with a quality of 0.2 at 120oC. Now some ice at 0oC is added to the cylinder. If the cylinder contains saturated liquid at 120oC when thermal equilibrium is established, determine the amount of ice added. The melting temperature and the heat of fusion of ice at atmospheric pressure are 0oC and 333.7 kJ/kg, respectively.
