Across
  1. 2. High-energy state of matter with charged particles (like lightning or the sun).
  2. 7. Phase change from a solid to a liquid; heat is added.
  3. 9. Phase change from a gas to a liquid; heat is removed.
  4. 12. Change A change that produces one or more new substances (e.g., rusting metal).
  5. 15. State of matter with definite volume but no definite shape; particles slide past each other.
  6. 17. Anything that has mass and takes up space.
  7. 18. Substance Matter that has a fixed composition and distinct properties (elements or compounds).
  8. 19. Type of vaporization that occurs on the surface of a liquid below its boiling point.
  9. 20. Mixture A mixture that looks the same throughout; evenly mixed (like air).
  10. 21. Change A physical change where matter changes state but not chemical composition.
Down
  1. 1. Change A change that affects form or appearance but does not create a new substance (e.g., melting ice).
  2. 3. Phase change from a solid directly to a gas; heat is added.
  3. 4. State of matter with definite shape and definite volume; particles vibrate in place.
  4. 5. Phase change from a gas directly to a solid; heat is removed.
  5. 6. Phase change from a liquid to a gas; heat is added.
  6. 8. State of matter with no definite shape or volume; particles move freely and rapidly.
  7. 9. Property A characteristic that describes a substance’s ability to form new substances (e.g., flammability, reactivity).
  8. 10. Mixture A mixture where the parts are visibly different (like salad or trail mix).
  9. 11. Two or more substances physically combined but not chemically bonded.
  10. 13. A pure substance made of only one kind of atom.
  11. 14. A substance made of two or more elements that are chemically combined.
  12. 16. Phase change from a liquid to a solid; heat is removed.
  13. 21. Property A characteristic that can be observed or measured without changing the substance’s identity (e.g., color, density, melting point).
