The pressure in an automobile tire depends on the temperature of the air in the tire. When the air temperature is 25 degC, the pressure gage reads 210 kPa. If the volume of the tire is 0.025 m^3, the pressure rises in the tire when the air temperature in the tire rises to 50 degC. Determine the amount of air, in kg, that must be bled off to restore pressure to its original value at this temperature. Assume the atmospheric pressure to be 100 kPa
