A. A rigid insulated tank has two compartments: Initially one contain 0.5 kmol of carbon dioxide (C02) at 27°C, 2 bar and the other contains l kmol of oxygen (02) at 152°C, 5 bar. The gases are allowed to mix while 500 kJ of energy are added by electrical work. Determine (a) the final temperature, in°C (b) the final pressure, in bar (c) the change in energy, in kJ. for T0 = 20°C (d) the energy destruction, in kJ. B.An insulated tank has two compartments connected by a valve. Initially, one compartment contains 0.7 kg ofC02 at 500 K, 6.0 bar and the other contains 0.3 kg ofN2 at 300 K, 6.
