6.113 A rigid, insulated tank whose volume is 10 L is initially evacuated. A pinhole leak develops and air from the surroundings at 1 bar, 258C enters the tank until the pressure in the tank becomes 1 bar. Assuming the ideal gas model with k 5 1.4 for the air, determine (a) the final temperature in the tank, in 8C, (b) the amount of air that leaks into the tank, in g, and (c) the amount entropy produced, in J/K.
