Two tanks are initially separated by a closed valve. Tank A is insulated and contains 1 kg of O₂ at 15°C and 300kPa. Tank B exchanges heat with the surrounding at 30°C to maintain thermal equilibrium and contains 2m³ of N₂ at 500kPa. The valve is opened and the two tanks are allowed to mix and reach thermal equilibrium with the surroundings. Find the final pressure in the tanks (kPa), the heat transferred during this process (kJ/kg), and the entropy generated during this process.
