Entropy as spreading out

Entropy as spreading out

Particle diagrams of the same substance as a solid, liquid, and gas with entropy increasing from solid to gas

Entropy, symbol SSS, measures how spread out particles and energy are. For the same substance, solids have the lowest entropy, liquids are higher, and gases are highest because gas particles have far more possible arrangements.
