A rigid 14-L vessel initially contains a mixture of liquid water and vapor at 100°C with 12.3 percent quality. The mixture is then heated
until its temperature is 180°C. The final state is superheated water and the internal energy at this state should be obtained by
interpolation. Calculate the heat transfer required for this process. Use data from the steam tables.

Thermodynamics Question:
An insulated rigid tank is divided into two equal parts by a partition. Initially, one part contains 6 kg of an ideal gas at 800 kPa and 50 oC, and the other part is evacuated (pressure in the other part is zero). The partition is now removed, and the gas expands into the entire tank. What can be said about the final temperature of the gas? (Consider Joule’s experiment)

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. Determine the heat transfer during this process by treating the mixture as a nonideal gas and using Amagat’s law. The universal gas constant is Ru = 8.314 kPa·m3/kmol·K.
