1. On a summer day, you take a road trip through Death Valley, California, in an antique car. You start out at a
temperature of 18°C, but the temperature in Death Valley will reach a peak of 48.5°C. The tires on your car
hold 10.5 L of nitrogen gas at a starting pressure of 2.45atm. The tires will burst when the internal pressure
(Pb) reaches 2.55atm. Answer the following questions and show your work.

How many moles of nitrogen gas are in each tire?
a. What equation will you use?
b. What variable are you solving for?
c. Fill in the equation with the values from the table above
d. Solve:
What will the tire pressure be at peak temperature in Death Valley?
a. What equation will you use?
b. What variable are you solving for?
C.
Fill in the equation with the values from the table above:
d. Solve:
Will the tires burst in Death Valley? Explain.
a. What information do you need?
b. What variable is the burst pressure from the table above?
C.
How does your peak pressure compare to the burst pressure?
If you must let nitrogen gas out of the tire before you go to what pressure must you reduce the tires
before you start your trip? (Assume no significant change in tire volume. This is a two-step calculation.)
a What equation will you start with?
b. What are the values for the variables you need?
C. How does the equation and variables change to calculate the final answer?
