A piston-cylinder device contains 6 kg of H2 and 21 kg of N2 at 160 K and 5 MPa. Heat is now transferred to the device, and the mixture expands at constant pressure until the temperature rises to 200 K. Assuming constant specific heats at room temperature and T0 = 20°C, determine: (I) the heat transfer during this process, and (II) the total entropy change associated with the process treating the mixture:
