  1. 4. Relatively fast form of vaporization that as the substance is heated the particle's energy creates a pressure equal to the air pressure outside the liquid
  2. 8. Change of state from a solid directly to a gas
  3. 9. Is a pure substance consisting of atoms of two or more different elements that are chemically combined
  4. 10. Change of state from a gas directly to a solid
  5. 11. State of matter in which the molecules of the substance move but the movement is free but restricted

  11. 23. Relatively slow form a 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
  12. 25. A material made of only one kind of element or compound; it is not a mixture
  13. 27. Change of state from a liquid to a solid
  14. 31. Law that states that matter can not disappear, but changes states

  13. 20. They have a uniform appearance; also known as a solution
  14. 24. Change of state from solid to liquid
  15. 26. Temperature at which a liquid starts to boil
  16. 28. State of matter in which the molecules of the substance are between a liquid and a gas
  17. 29. State of matter in which the molecules of the substance do not move/retrained
  18. 30. Space enclosed or occupied by an object
