Question

Why air expands inside the tyre as we drive our vehicle?

Answer 1

when we drive , the frictional force between the tires and the road increases the temperature of the air inside the tire.

According to Gay-Lussac's Law,

p ∝ T ; [When volume is constant]

so the increase in temperature also increases tire pressure.

Answer 2

Answer:

• The road increases the tyre pressure when we are driving our car.

• Due to the high pressure force produced by the friction, the air inside the tyre warms up and causes the tyre to expand.

• Friction transfers energy to the air inside the tyre, raising its temperature as a result.

• Now, in accordance with Charles' Law, the pressure of the gas in the tyre rises because the law of pressure states that P is directly proportional to T, P∝ T and the volume of the tyre stays constant.

• In simply we can say that, air expands inside the tyres as we drive our vehicle because the air inside the tyres heats up as a result of the tyres. Air expands when it warms up. Naturally, this results in higher tyre pressure.
