6 Physical States of Matter solid: -non compressible -definite shape and volume liquid: - slightly compressible -flows -indefinite shape -definite volume gas: -readily compressible -indefinite shape and volume -takes shape of the container

7 Changes of State Process of changing from one physical state to another melting solid to liquid state freezing (or solidification) liquid to solid state evaporation (or boiling) liquid to gas condensation gas to liquid state sublimation solid to gas state (without going through liquid state) deposition gas to solid state (without going through liquid state)
