The tire on a bicycle stored in a cool garage at 18 °C had a pressure of 80. psi. What is the pressure inside the tire after riding the bike at 43 °C?
Analysis
Since this question deals with pressure and temperature, Gay–Lussac’s law is used to determine a final pressure because three quantities are known—the initial pressure and temperature (P_{1} and T_{1} ), and the final temperature (T_{2} ).
