An automobile tire is inflated (while cold) to a volume of 11.8 L and a 'gauge pressure' of 36.0 psig at a temperature of 12oC. Driving on a hot day, the tire warms to 65oC and its volume expands to 12.2 L. When the tire pressure is measured again it is psig. (Note: the 'gauge pressure is the difference between the total pressure and the atmospheric pressure. Assume that the atmospheric pressure is 14.7 psi)
