The pressure in an automobile tire depends on the temperature of the air in the tire. When the air temperature is 25°C, the pressuregage reads 210 kPa. If the volume of the tire is 0.025 m3, determine the pressure rise in the tire when the air temperature in the tirerises to 60°C. Also, determine the amount of air that must be bled off to restore pressure to its original value at this temperature.Assume the atmospheric pressure to be 100 kPa.
