How is does the partucale theory of matter help explain how a hand bicycle pump and tire valve operate?

The particle theory of matter states that all matter is made up of tiny particles called atoms and molecules. These particles are in constant motion and are attracted to each other by forces of attraction. When a force is applied to a gas, such as air, the particles move closer together and the gas becomes denser. This increase in density increases the pressure of the gas.

In a hand bicycle pump, when the piston is pushed down, it compresses the air inside the pump. This compression forces the air particles closer together, increasing the pressure of the air. The increased pressure forces the air out of the pump and into the tire.

The tire valve is a one-way valve that allows air to flow into the tire but not out. This prevents the air from escaping from the tire when the pump is removed.

The particle theory of matter helps to explain how a hand bicycle pump and tire valve operate by showing how the movement and interactions of particles can create changes in pressure and allow air to flow in and out of the tire.
