Each tire of an automobile is equipped with a relief valve such that the pressure inside the tire will not exceed 240 kPa (gage). A motorist starts a trip with a tire pressure of 200 kPa (gage) and an air temperature of 23oC in each tire. Initially, each tire contains 0.11 kg of air. During the long drive, the temperature of the air inside the tires reaches 83oC. (a) Determine the mass of air that escaped each tire over the course of the trip. (b) What will the tire pressure be when the air inside the tires (at end of trip) returns to 23oC? Hint: For part (a), you may assume the max pressure was reached (state 2), which allowed the air to escape.
