Down
  1. 1. Change of state from a liquid to a solid
  2. 2. State of matter in which the molecules of the substance are between a liquid and a gas

  5. 5. Distinct groups of two or more atoms
  6. 8. Does not have a uniform appearance since the substances are unevenly distributed
  7. 12. A relatively slow form of vaporization in which particles on the surface of the liquid state obtain sufficient energy to change to the gaseous state through the random collisions with particles
