Solids Liquids & Gases

Classifying solids liquids & gases

solid-liquid=melting

liquid-solid=freezing

liquid-gas=boiling

gas-liquid=condensing

solid-gas=sublimation

gas-solid=deposition

Particle model theory

all substances made from particles

particles attracted to each other some strongly some weakly

particles are always moving

particles move faster when warmer

particles move slower when colder

tiny spaces beteween particles

compressed=pushed or squeezed into a smaller area
