A driver measures her "cold" tire gauge pressure to be 2.05 105 Pa. The measurement is made before driving, when the tires are at the temperature of the surroundings, 18.0° C. After driving several miles, she checks the gauge pressure again and finds that it has increased to 2.16 105 Pa. Find the final temperature in Celsius of the air in the tires, assuming negligible change in volume.
