4. Terms for state change diagram Freezing or Solidification Melting or Liquefecation Sublimation Evaporate or Vaporization Condensation

5. Changes of State Change of State: Evaporation: Condensation: Sublimation:

6. Changes of State Occurs due to a change in the temperature of matter Change of state from liquid to gas Change of state from gas to liquid Change solid to gas (dry ice)

7. Changes of States Melting Point: Boiling Point Boiling point varies depending on altitude! –Lower altitudes = –Higher altitudes =

8. Changes of States the temperature at which a solid turns to a liquid the temperature at which a liquid turns to a gas = higher boiling point (New Orleans, Louisiana at sea level) = lower boiling point (Denver, Colorado in the mountains)
