  1. PHASE CHANGES

  2. BOILING • a type of phase which occurs when a liquid is heated to its boiling point and changes to a gas. • Endothermic

  3. The melting point of a solid is the temperature at which the solid becomes a liquid. Endothermic MELTING

  4. Condensation is the change of water from its gaseous form (water vapor) into liquid water. Exothermic CONDENSATION

  5. Sublimation is the transition of a substance from the solid phase to the gas phase without passing through the liquid phase. Endothermic SUBLIMATION

  6. When a liquid turns to a solid Exothermic FREEZING

  7. Evaporation is when a liquid turns to a gas below the boiling point. Endothermic EVAPORATION

  8. QUIZ TIME!!!! • What is the difference between exothermic and endothermic? • What is one example of freezing? • A great definition for sublimation is? • When dry ice starts to turn into steam/fog, what is it called? • When you get out of the shower, how come there is steam on the mirror?

  9. THE END!!!!!
