Transient Analysis A tank whose volume is 0.01 m is initially evacuated. A pinhole develops in the wall, and air from the surroundings at 21C, 1 bar enters until the pressure in the tank is 1 bar. If the final temperature of the air in the tank is 21C, determine (a) the final mass in the tank, in g, and (b) the heat transfer between the tank contents and the surroundings, in kJ.
