Starting out a trip from a mountain, you inflate the tires on your car to a pressure of 321kPa (Pi) when the temperature is -5C. You drive to the beach, where the temperature is 28C . a)what is the final pressure (Pf) in the tires, assuming constant volume? Assume that the air behaves as an ideal gas and that the number of moles (N) in the tires is constant. ignore expansion of the tire.
