* Low density: Gases have a very low density compared to liquids and solids. This means the particles are spread out over a large volume.
* Weak intermolecular forces: The forces of attraction between gas particles are very weak. This allows them to move freely and independently of each other.
* High kinetic energy: Gas particles have high kinetic energy, meaning they are constantly moving and colliding with each other and the walls of their container.
Think of it like this: imagine a room full of people, but instead of people, there are tiny, invisible particles bouncing around. They are constantly bumping into each other and the walls, but they aren't stuck together like in a solid.
This loose arrangement and constant movement are the key characteristics of gases, giving them their unique properties like compressibility and expandability.
