Two insulated tanks are connected by a valve. One tank initially contains 0.5 kg air at 80 degree C, 1 bar, and the other contains 1.0 kg of air at 50 degree C, 2 bar. The valve is opened and the two quantities of air are allowed to mix until equilibrium is attained. Employing the ideal gas model with c_v = 0.72 kJ/kg middot K, determine A) The final temperature, in degree C. B) The final pressure, in bar. C) The amount of entropy produced, in kJ/K.
