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 1.5 m² of air at 400 K, 4 bar. On the other side is 1.5 m³ of air at 400 K, 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.
