An automobile tire has a volume of 0.0141 m^3 on a cold day when the temperature of the air in the tire is 5.3°C and atmospheric pressure is 1.02 atm. Under these conditions, the gauge pressure is measured to be 1.7 atm (about 25 lb/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°C and the volume has risen to 0.0152 m^3. What then is the gauge pressure?
