Across
  1. 2. process where heat energy is released into the environment
  2. 3. state of matter where to molecules are moving extremely fast and ions are stripped off the atoms; no fixed shape or volume
  3. 4. point temperature at which a liquid becomes a gas or vapor
  4. 6. change in the state of matter when energy is absorbed or released
  5. 7. process of changing from a gas to liquid
  6. 11. point temperature at which a liquid becomes a solid
  7. 12. state of matter where the molecules are close but are able to move and has a fixed volume but not fixed shape
  8. 14. energy of movement of the substance or particles within the substance
  9. 15. anything that has mass and has a volume
  10. 18. process in which an atom or a molecule gains or loses electrons to form charged ion
  11. 19. process of changing from a liquid to a solid
  12. 21. changing of a solid into a liquid
  13. 22. process of changing directly from a gas to solid
Down
  1. 1. removal of ions from a substance
  2. 2. changing of a liquid into a gas
  3. 5. process where heat energy is absorbed from the environment
  4. 8. measure of the average motion of the particles
  5. 9. state of matter where the molecules are in a rigid and vibrating, fixed volume and fixed shape
  6. 10. process of changing directly from solid to a gas
  7. 13. point temperature at which a solid becomes a liquid
  8. 16. amount of matter in an object
  9. 17. amount of space an object takes up
  10. 20. state of matter where the molecules are moving quickly; does not have fixed shape or fixed volume
