One kg of Refrigerant 22, initially at pi = 0.9 MPa, u= 232.92 kJ/kg, is contained within a rigid closed tank. The tank is fitted with a paddle wheel that transfers energy to the refrigerant at a constant rate of 0.1 kW. After 20 minutes of stirring, the refrigerant is at p2 = 1.2 MPa, u= 276.67 kJ/kg. No overall changes in kinetic or potential energy occur. Determine the work and heat transfer for this process, each in kJ.
