Air pressure in a car tyre increases during driving. Explain.

We know that when we drive there is static friction between the tire and the road which increases the temperature of the rubber of the tire and hence the air inside it.


According to ideal gas equation and Gay Lussac’s law which states that states that, for a given mass and constant volume of an ideal gas, the pressure exerted on the sides of its container is directly proportional to its absolute temperature.



Thus, increase in temperature causes increase in pressure too.
