Question

Put the following events in the correct order to describe what happens when a bicycle tyre is slowly deflated by opening the valve.

Accepted Answer

The number of gas particles inside the tyre decreases — The correct sequence is: C → A → D → B. Gas escapes through the valve (C), reducing the number of particles inside (A). Fewer particles mean fewer collisions per second with the walls (D), which results in a lower pressure inside the tyre (B).

Answer

Gas particles escape through the open valve to the atmosphere

Answer

The pressure inside the tyre drops below initial value

Answer

The remaining particles collide with the tyre walls less frequently overall

Answer

The number of gas particles inside the tyre decreases
