Question
Air pressure in a car tyre increases during driving. Explain.
Solution
During driving, the temperature of the gas inside the tyres increases due to the application of the reaction force on the tyres. But the volume of gas inside the tyre is constant. So, according to the Charles law P ∝ T, the air pressure of car tyres increases.
