Tank A contains 50 kg of
freon-12 at 0.5Mpa, at 20 C Tank B is initially empty. The valve is
cracked open. The valve remains open. The process ends with both
tanks in equilibrium at 0 C saturated vapor. Find the mass in each
tank at the end, Q, change is s for tanks, change in sec for
surrounding and for the universe, Wcv and Wrev.
