The pressure in an automobile tire depends on the temperature of the air in the tire. When the air temperature is 25 degrees C, the pressure gage reads 205 kPa. If the volume of the tire is 0.021 m³, determine the amount of air that must be bled off to restore pressure to its original value if the air temperature in the tire rises to 38 degrees C. Assume the atmospheric pressure to be 100 kPa. The gas constant of air is R=0.287 kPa m³/(kg. K) .
