An air line at 100 psi and 70°F is used to fill the 2800-in3 tire of a vehicle that contains air at only 5 psi and 70°F. Assuming negligible heat transfer from the rigid tire during filling, estimate the temperature of the air in the tire when the pressure reaches 35 psi. Also, estimate the added mass of air. Assume that the conditions in the air line remain constant and that Patm = 15 psia.
