A car tire contains 0.0440 m3 of air at a pressure of 2.75 x 10° N/m2 (about 40 psi). How much more internal energy (in J) does this gas have than the same volume has at zero gauge pressure
(which is equivalent to normal atmospheric pressure)? (Assume the tire pressure of 2.75 x 105 N/m2 is absolute pressure, not gauge pressure. Assume for this question that air is monatomic.)
