Air is contained in a rigid, well-insulated container
of volume 3 m3. The air undergoes a process from
an initial state with a pressure of 200 kPa and temperature of 300
K. During the process, the air
receives 720 kJ of work from a paddle wheel. Model the air as an
ideal gas with constant specific
heats. Evaluate the specific heats at 300 K. Neglect changes in
kinetic energy and potential energy.
Determine the mass of the air in kg, the final temperature of the
air in K, and the amount of entropy
generated by irreversibilities during the process in kJ/K.

An initially empty, well insulated, rigid tank with a volume of
2 m3 is fitted with a mixing device. The tank has two inlets and
zero outlets. One inlet is water at 1 MPa and 600◦C while the other
