The pressure in an automobile tire depends on the temperature of the air in the tire. When the air temperature is 25 °C the pressure gage reads 310 kPa absolute. If the volume of the tire is 0.025 m3, determine the pressure rise in the tire when the air temperature in the tire rises to 50 °C. Also determine the amount of air that must be bled off to restore the pressure to its original value at this temperature.
