chem phase changes x physical separation technique

Sublimation

the phase change where a solid changes directly to gas without becoming a liquid first

Deposition

the phase chan ge where a gas changes directly into a solid without becoming a liquid first

Vaporization

liquid changes into a gas, includes boiling and evaporating

Condensation

the phase change where a gas changes into a liquid

melting

the phase change where a solid becomes a liquid when heat is added

freezing

the phase change where a liquid becomes a solid when heat is removed

distillation 

used to separate liquids based on different boiling points 

crystallization

used to purify a solid by forming crystals from a solution

decanting

used to separate liquid from solids or heavier liquids by pouring off the top layer

filteration

used to separate a solid from a liquid by using a filter
