The manufacturer of your tires suggests that your tires should be filled with air at 25 oC to a pressure of 35 PSI (Pounds per Square Inch). Since you are going on a road trip to Pittsburg, you decide to put in extra air and fill the tires to 45 PSI to get better gas mileage. On the way to Pittsburg, due to friction, the temperature of the air in the tires reaches 75 oC. What would the pressure of the air in the tires be at this point in the trip?
a) ~12 PSI
b) ~35 PSI
c) ~135 PSI
d) ~53 PSI
