When my car has been parked for a while, its tires look a wee bit ‘low,' and, when their pressure is measured at 23 C (in the garage) it is found to be 320 kPa. After the car has been driven some distance, the tires look ?ne and their measured pressure has increased to 360 kPa. What is the temperature of the air inside the tires, once they have warmed up?
