A driver measures her "cold" tire gauge pressured to be 1.93x10^5 Pa. The measurement is made before driving, when the tires are at the temperature of the surroundings, 20.0 ° C. After driving several miles, she checks the gauge pressure again and finds that it has increased to 2.20x10^5 Pa. Find the final temperature  of the aire in the tires, assuming negligible change in volume.

An automobile tire is inflated with air originally at 10.0°C and normal atmospheric pressure. During the process, the air is compressed to 27.0% of its original volume and the temperature is increased to 39.0°C. (a) What is the tire pressure in pascals? Pa (b) After the car is driven at high speed, the tire's air temperature rises to 85.0°C and the tire's interior volume increases by 3.00%. What is the new tire pressure (absolute) in pascals? Pa

Large helium-filled balloons are used to lift scientific equipment to high altitudes. a) What is the pressure, in atmospheres, inside such a balloon if it starts out at sea level with a pressure of one atmosphere and a temperature of 10.0°C and rises to an altitude where its volume is twenty times the original volume and its temperature is -49.5°C ?  b) What is the gauge pressure, in atmospheres, in the balloon then? (Assume the atmospheric pressure is constant.)

An industrial firm supplies compressed air cylinders of volume 0.25 m3 filled to a pressure of 20×106 Pa at 17 ºC. Calculate the number of moles of air in each cylinder.
