A car tire has a recommended rating of 2.518 atm. While parked, the tire has at the temperature of
11.00C, inflated to a volume of 10.4 L and with a pressure of 2.109 atm. When driving on a hot day, the
tire warms to 62.0 Cand its volume expands to 10.9 L
a) Assuming there are the same molecules in the tire (n is constant) Does the pressure in the
tire exceed its recommended rating on the hot day?
b) Find the number of moles in the tire
c) Convert your answer in A to mmHg
d) Knowing the number of mols in the tire use the Ideal Gas law to calculate the final pressure
at 62 C, is it the same as your answer in A
e)
While parked (11 C) you inflated the tire to 2.38 atm assuming there is no temperature
change what is the new volume of the tire?
f) Once you finish your drive, the tire temperature is 62 oC, after 10 minutes of being parked
the temperature of the tire is now 580C assuming your tire volume does not change what is
the new pressure of the tire? (get the original pressure form C)
g) You are driving and hit a pothole at full speed, your tire volume momentarily changes from
10.9 to 10.7 Liters. What was your tire pressure when you hit the pothole? Use your initial
pressure from answer A and assume there was no temperature change.
h) If the atmospheric composition is: Nitrogen (78.1%), Oxygen (20.9%), Argon (0.93%), Carbon
Dioxide (0.04%). From your answer in e What is the partial pressure of each of the gases in
your tire?
