When the air temperature in an automobile tire is 25oC, the pressure gage reads 210 KPa. If the air volume in the tire is 0.025 m^3 and the atmospheric air pressure is 110 Kpa.
a) Determine the tire pressure rise when the air temperature in the tire rises to 50oC assuming that the volume does not change.
b) Determine the amount of the air (kg) that must be bled off to restore the pressure to its original value at this temperature assuming that the volume does not change.
