Question

When a car is driven for a long time, the pressure of air in the tires increases. This is best explained by which of the following gas laws??  
A. Boyle’s Law  
B. Charles’s Law  
C. Gay Lussac’s Law  
D. Dalton’s Law

Accepted Answer

Correct Answer: (C)Gay Lussac’s Law. 
Rationale: The increase in air pressure inside car tires after long driving is explained by Gay-Lussac’s Law.When a car is driven for an extended period, friction between the tires and the road, as well as flexing of the tire rubber, causes the air inside the tires to heat up. The volume of a tire remains nearly constant, so an increase in temperature leads directly to an increase in pressure. This direct relationship between temperature and pressure at constant volume is described by Gay-Lussac’s Law.A) Boyle’s LawBoyle’s Law describes the inverse relationship between pressure and volume at constant temperature. In a car tire, the volume does not significantly change during driving, so this law does not explain the observed increase in pressure.B) Charles’s LawCharles’s Law relates volume and temperature at constant pressure. Because the tire’s volume is constrained and pressure is not held constant, this law does not apply to the situation.C) Gay Lussac’s LawGay-Lussac’s Law states that pressure is directly proportional to temperature when volume is constant. As the air inside the tire heats up, the kinetic energy of the gas molecules increases, causing more frequent and forceful collisions with the tire walls. This raises the pressure, matching what happens during prolonged driving.D) Dalton’s LawDalton’s Law concerns the total pressure of a mixture of gases and the contribution of each gas’s partial pressure. The composition of air inside the tire does not change during driving, so this law is not relevant.ConclusionAn increase in temperature at constant volume leads to an increase in pressure. This relationship explains why tire pressure rises during long drives and is described by Gay-Lussac’s Law.
