An automobile tire has a volume of 1.60 x 10-2 m3 and contains air at a gauge pressure (pressure above atmospheric pressure) of 167 kPa when the temperature is 0.00°C. What is the gauge pressure (in kPa) of the air in the tires when its temperature rises to 27.0°C and its volume increases to 1.69 x 10-2 m3? Assume atmospheric pressure is 1.01 x 105 Pa.

    You have to convert gauge pressure to atmospheric, then work the problem, and in the end, convert back to gauge pressure.
