Phase Changes

 

All of these may be explained by an appreciation of the energy overcoming the forces holding the particles together or becoming insufficient to keep them apart.

fusion, melting: solid to liquid phase change

boiling, vaporization: liquid to gas phase change ***evaporation: liquid to gas phase change below the boiling point

solidification, freezing: liquid to solid phase change

condensation: gas to liquid phase change

sublimation: Solid to gas phase change

deposition: gas to solid
