During a long journey, friction with the road causes the air inside a car tyre to heat up, which increases the air pressure. The volume of the tyre remains constant and there are no air leaks.
Why does the pressure increase?
The air molecules in the tyre move more quickly.
The air molecules in the tyre increase in size.
The air molecules in the tyre stop colliding.
The volume of the air in the tyre decreases.
