Question

The pressure in the tire is higher than the pressure of the air outside the tire. Explain what causes the pressure of the air inside the tire.

Answer 1

Answer:

The increase in temperature increases the kinetic energy, and hence the speed, of the air molecules in the tyre. The increased speed of the molecules will increase the number of collisions per second with the tyre wall. This in turn results in an increased force, and therefore increased pressure on the tyre wall
