Which container has higher pressure?

• Container A

• Container B

• Container A and B have the same pressure.

When a cold tire is inflated to a certain pressure and then is warmed up due to friction with the road, the pressure increases. This happens because the

• air molecules hit the walls of the tire less frequently

• rubber in the tires reacts with oxygen in the atmosphere

• air molecules speed up and collide with the tire walls more often

• air molecules diffuse rapidly through the walls of the tire.
