Two tanks are connected by a valve. Tank A contains air at 200 kPa, volume of A = 0.5 m^3, and temperature of A = 30oC. Tank B is empty and has double the volume of Tank A. The valve is now open and the two tanks come to a uniform state. If the final temperature of the process remains constant, determine (a) the mass (kg), (b) the final pressure, (c) the initial and final specific volume (m^3/kg), and (d) the compressibility factor at each state.
