An automobile tire has a volume of 0.0150 m3 on a cold day when the temperature of the air in the tire is 50°C and atmospheric pressure is 1.02 atm. Under these conditions the gauge pressure is measured to be 1.70 atm (about 25 1b/ine2)A. fter the car is driven on the highway for 30 min, the temperature of the air in the tires has risen to 45.0°C and the volume to 0.0159 m3. What then is the gauge pressure?
