In solids, the particles are closely packed together. The closely packed arrangement is what causes solids to have defined shapes. The solid state of matter has the lowest energy compared to the same substance in the other two states.
Particle Arrangement in Liquids
In liquids, the particles are near each other, but not tightly packed. The particles in a liquid are able to slide past each other. This allows for movement of particles throughout the liquid. The looser arrangement of particles is what allows liquids to take on the shape of their container. The intermolecular forces between particles in liquid determine properties like viscosity and surface tension. Particles in a liquid are higher in energy than the solid state, but lower in energy than the gas state.
Particle Arrangements in Gases
Gases have particles that are very far away from each other. These particles are very energetic. The arrangement of particles in a gas is why gases will expand to fill whatever space they occupy. Gas particles have the weakest intermolecular interactions compared to solids and liquids.
