A car tire was inflated to a gauge pressure of 22.0 psi on a cold day when the temperature was -3degree C. What pressure will be found on the tire gauge on a warmer day when the temperature is 31degreeC? Assume an average atmospheric pressure at sea level and that the tire does not leak or expand. [ ]psi What if the tire had expanded by 2.00 %? What would the gauge read on the warmer day? [ ]psi

The gauge pressure in each of the four tires of an automobile is 240 kPa . If each tire has a "footprint" of 150 cm2 (area touching the ground), determine the mass of the car. Express your answer to two significant figures and include the appropriate units.
Before going on a ski trip to Tahoe, you inflated your car tires to the recommended...
Before going on a ski trip to Tahoe, you inflated your car tires to the recommended pressure of 230 kPa (gage pressure, measured at sea level). Right on arrival at the lake of 6,225 ft elevation, you check the gage pressure again and it reads 260 kPa. Assuming the volume of the tire remained constant at 10 L, determine the percent increase in the temperature of the air in the tire.You can assume an averaged atmospheric air density of1.11kg/m3for this...

At sea level, water boils at 100 °C, and the absolute atmospheric pressure is 101 kPa. As the atmospheric pressure above water decreases, the temperature required for boiling also decreases, at a rate of 3.1 kPa per "C. For the system shown below: a. What is the absolute atmospheric pressure at an elevation of 4100 m, assuming a constant unit weight of air of 11.80 N/m3? b. What will be the boiling temperature for water at this elevation?
