  21. Physical vs. Chemical Changes • Phase changes are all classified as physicalchanges 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.

  22. 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

  23. 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)

  24. 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
