* Solids: Particles in solids are tightly packed together and vibrate in fixed positions. They have the least amount of kinetic energy (energy of motion).
* Liquids: Particles in liquids are closer together than gases but have more freedom to move around. They have more kinetic energy than solids.
* Gases: Particles in gases are far apart and move rapidly in random directions. They have the most kinetic energy out of the three states.
In summary: The lower the kinetic energy of the particles, the less they move, and the more likely they are to be in a solid state.
