The pressure in a car tire depends on the air temperature in the tyre. At 25°C air temperature, a pressure gauge shows 210 kPa (gage). The air volume in the tire is 25 liters and can be assumed to be constant. The atmospheric air pressure can be set to 100 kPa. a) Calculate the increase in pressure if the temperature in the tire is increased to 50°C. b) How much air (in g or kg) must be let out of the tire if you should have 210 kPa (gage) in the tire at the new temperature?
