22 Physical vs. Chemical Changes  Phase changes are all classified as physical changes because in chemical changes an entirely new substance is produced.  In chemical changes, the compounds rearrange to form new compounds.  In physical changes the compounds don’t change at the molecular level.

23 Energy (usually in the form of heat)  Energy is added or taken away to create phase changes.  When energy is added, particles move further apart.  Solid  Liquid  Gas  When energy is taken away, particles move closer together.  Gas  Liquid  Solid

24 Phase Changes  Melting = solid  liquid  Freezing = liquid  solid  Boiling / Vaporization / Evaporation = liquid  gas  Condensation = gas  liquid  Sublimation = solid  gas (ex: dry ice)  Deposition = gas  solid (very rare)

25 Temperature and Pressure Points of change  Melting Point = T & P when solid  liquid  Freezing Point = T & P when liquid  solid  Boiling Point = T & P when liquid  gas  Condensation Point = T & P when gas  liquid
