1. The particle model of matter states that all matter is made up of tiny particles. In the case of gases, these particles are atoms or molecules.

2. These particles are in constant, random motion. They move in straight lines until they collide with another particle or the walls of their container.

3. The particles in a gas are far apart from each other and have high kinetic energy. This means they move faster and in more random directions than the particles in solids or liquids.

4. When a gas is introduced into a container, the particles start to move and spread out in all available space. They continue to move and spread until they have evenly filled the entire container.

5. This is because the particles are in constant motion and will move to fill any available space. They will also bounce off the walls of the container and spread out again, continuing this process until the gas has evenly filled the container.

6. Therefore, the particle model explains that a gas spreads out to fill a container due to the constant, random motion of its particles and the large amount of space between them.
