Across
  1. 2. Changes / a physical change, a substance changes state when its energy increases or decreases by a sufficient amount
  2. 5. point / temperature at which a liquid changes into a solid
  3. 8. / reverse of vaporization, occurs when liquid particles lose enough thermal energy to become a liquid
  4. 9. / vaporization that takes place only at the surface
  5. 10. / occurs when particles of a liquid gain enough thermal energy to move independently
Down
  1. 1. energy / total kinetic and potential energy of all the particles
  2. 3. / occurs when the particles of a substance gain so much thermal energy that the attractions between particles are completely overcome
  3. 4. / changing from solid to liquid and occurs when a solid absorbs enough thermal energy to make its particles vibrate so fast that they break free from their fixed positions
  4. 6. / reverse of melting, occurs when liquid particles lose enough thermal energy that the particles slow down so much that they form regular patterns
  5. 7. / water vapor escaping and when vaporization takes place in the whole substance because the entire substance is being heated.
