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. The gas constant of air is R = 0.287kPa-m² )= 0. 287 kPa mkg-Kkg-KkJ336 kPa.The pressure rise in the tire isThe amount of air that must be bled off to restore pressure to its original value is 0.0070 kg.
