An automobile tire has a volume of 0.0150 m3 on a cold day when the temperature of the air in the tire is 5.0oC and atmospheric pressure is 1.02 aims. Under these conditions the gauge pressure is measured to be 1.70 atm (about 251b/in.2). After the car is driven on the highway for 30 min, the temperature of the air in the tires has risen to 45.0oC and the volume has risen to 0.0159 m3. What then is the gauge pressure?
