A rigid tank whose volume is 10L is initially evacuated. A pinhole develops in the wall, and air from the surroundings at 1 bar, 25 degrees Celsius enters until the pressure in the tank becomes 1 bar. NO significant heat transfer between the contents of the tank and the surroundings occurs. Assuming the ideal gas model with k=1.4 for the air, determine (a) the final temperature in the tank, in degrees Celsius, and (b) the amount of air that leaks into the tank, in g.
