If you have a car with TPMS, it monitors the pressure in your tires continuously. As you were driving to class on January 11, the temperature of the air in your tires got up to 45 C from friction with the road, and the TPMS sensor measured 35 psi. While you were sitting in physics class the temperature dropped to -2 C. We were in class for 2.5 hours, and let us assume that was enough time for the temperature of your car, tires, and air inside the tires to come to equilibrium with the outside. What pressure would your TPMS sensor have measured when you started your car after class?
