Problem 2 (20 pts; Show your work for partial credits) As shown in the figure, an insulated box is initially divided into halves by a frictionless, thermally conducting piston. On one side of the piston is 1.5m3 of air at 400K,4 bar. On the other side is 1.5m3 of air at 400K,2 bar. The piston is released, and equilibrium is attained, with the piston experiencing no change of state. Employing the ideal gas model for the air, determine a) the final temperature, in K. b) the final pressure, in bar. c) the amount of entropy produced, in kJ/kg
