A rigid tank whose volume is 10 L is initially evacuated. A pinhole develops in the wall, and air from the surroundings at 1 bar, 22o C enters until the pressure in the tank becomes 1 bar. No significant heat transfer between the contents of the tank and the surroundings occurs. Suppose air behaves as an ideal gas and has variable specific heat. Determine, (a) The final temperature of air in the tank (o C). (b) The amount of air that leaks into the tank (in g).
