An automobile tire has a volume of 1 .64 x 10-2 m3 and contains air at a gauge pressure (pressure above atmospheric pressure) of 165 kPa when the temperature is 0.000C. What is the gauge pressure of the air in the tires when its temperature rises to 27 .00C and its volume increases to 1.67 x 10-2 m3? Assume atmospheric pressure is 1.01 x 105 Pa.
