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. hw to do this sum?
Use the ideal gas relation
where temps are in Kelvins
and pressure is in absolute. Absolute pressure=guage+atmospheric.
