Question

Air pressure in a car tyre is increased during driving. Why​

Answer 1

$\huge\mathbb{ANSWER}$

When a car is in motion,the temperature of air inside the tyre increases due to motion of the air molecules. According to Charles's law, pressure is directly proportional to the temperature.

Hence,if the temperature inside tyre increases,then the air pressure inside the tyre will also increase.

when the automobile is driven on the motorway, force of friction is produced between tyre and the road. the increase in velocity increases the number of collisions against the walls of the tyre. thus the pressure of the gas in tyre increases. the tyre due to the increase of pressure may burst.
