  1. 3. A pure substance consisting of atoms of two or more elements that are chemically combined in a fixed ratio
  2. 5. a property of a substance that describes how its chemical identity changes in the presence of another substances or under certain conditions
  3. 7. a pure substance that consists of atoms with the same atomic number
  4. 10. a change that alters the chemical composition of a substance
  5. 12. of matter The law that states that matter can neither be created nor destroyed, but can only change form
  6. 15. The state of matter in which particles vibrate in fixed positions, giving a substance a fixed shape and volume
  7. 18. Anything that has mass and occupies space

  16. 30. the force of gravity acting on the matter in an object
  17. 32. the space enclosed or occupied by an object
  18. 33. a mixture that does not have a uniform appearance since the combined substances are unevenly distributed
  19. 34. a physical combination of two or more substances in a changeable ratio
Down
  1. 1. anything about a substance that can be observed or measured without altering its chemical composition
  2. 2. The change of state from a gas (vapor) to a liquid
  3. 4. the change in state directly from a solid to a gas (vapor) without melting first
  4. 6. The relatively slow form of vaporization in which liquid particles obtain sufficient energy to change the gaseous state through random collisions of particles
  5. 8. the change in state directly from a gas (vapor) to a solid without condensing first
  6. 9. a material made of only one kind of element or compound
  7. 11. A mixture that has a uniform appearance throughout; also known as a solution, especially of a solid dissolved in a liquid
  8. 13. the building block of all matter; consists of protons, electrons, and usually neutrons

  10. 16. The change of state form a liquid to a solid
  11. 17. The change of state from a liquid to a gas (vapor)
  12. 19. The relatively fast form of vaporization in which the energy within the liquid creators higher pressure within the liquid then the air pressure outside the liquid
  13. 25. The state of matter in which particles are far apart, move rapidly, and have little interaction with each other
  14. 28. the temperature at which a solid turns into a liquid
  15. 31. the mass per unit volume of an object
