4.40 A rigid, insulated tank consists of two compartments of equal volume separated by a valve. Initially, one compartment contains air at a pressure of 750 kPa and a temperature of 50°C, while the second compartment is completely empty. The valve is opened and it remains open until the two compartments reach pressure and temperature equilibrium. Determine the final pressure and temperature of the air, assuming each compartment has a volume of 0.65 m'.
Problem 3-2 A rigid, well-insulated tank consists of two compartments eparated by a valve, one being twice the volume of the other.
