Across
  1. 4. the process of turning matter from liquid into vapor, usually using heat.
  2. 7. a form or condition that a substance can be in
  3. 8. a group of atoms bonded together
  4. 10. the process by which heat energy is transmitted through collisions between neighboring atoms or molecules.
  5. 13. turning a solid into a gas, not going through the state of a liquid.
  6. 14. involves a reaction wherein the product self-assembles and coats the substrate
  7. 16. the energy contained within a system that is responsible for its temperature
  8. 17. the process of burning something
  9. 18. becoming liquified by heat
  10. 20. a substance/matter that can move freely and has no fixed volume
  11. 21. a thermometer measures this
  12. 22. you can find this by dividing mass by volume
  13. 24. conversion of a substance from the liquid or solid phase into the gaseous (vapour) phase
  14. 25. a substance/state of matter that moves freely but has a fixed folume
Down
  1. 1. a law that says matter can not be created or destroyed
  2. 2. a thing that is composed of 2 or more molecules
  3. 3. and oxygen molecule has 2 of these
  4. 5. and arrow that shows which way the reaction is going.
  5. 6. there are 118 of these on the periodic table
  6. 9. a math-looking equation that represents a chemical reaction in which the reactants and products are shown
  7. 11. a number placed in front of a formula to balance a chemical equation
  8. 12. this form of energy is when the object is in motion
  9. 15. liquid does this when its temperature reaches below 32 degrees F
  10. 17. the process in which water in the air changes into liquid water.
  11. 19. the emission of energy as electromagnetic waves
  12. 23. a state of matter that retains its shape and density when not confined
