* Gas particles have a lot of space between them: Unlike solids and liquids, gas molecules are spread out and move freely. This means they can easily diffuse and spread out to fill any available space.
* Gas particles move rapidly: Gas molecules are constantly in motion, colliding with each other and the walls of their container. This rapid movement allows them to quickly disperse throughout a room.
