Across
  1. 1. A physical change which depends on the movement of atoms/molecules in a substance
  2. 7. the unit of energy
  3. 8. moderate energy phase of a substance in which particles can move around, but have a fixed volume
  4. 10. a reaction that releases energy; creates a warming sensation
  5. 12. the absorption of energy which takes a substance from solid to liquid
  6. 13. the absorption of energy which takes a substance from liquid to gas
  7. 14. the release of energy which takes a substance from gas to liquid
  8. 15. the rapid release of energy which takes a substance from a gas to solid
  9. 16. the ability to do work
  10. 17. highest energy phase of a substance in which particles can move around freely, does not have a fixed volume or shape
Down
  1. 2. lowest temperature theoretically achievable, when all molecules/atoms stop movement completely
  2. 3. a reaction that absorbs energy; creates a cooling sensation
  3. 4. associated with temperature and deals with vibrations of atoms/molecules
  4. 5. the rapid absorption of energy which takes a substance from solid to gas
  5. 6. the amount of energy required to change 1 gram of a substance by 1 degree celsius
  6. 9. the release of energy which takes a substance from a liquid to solid
  7. 11. lowest energy phase of a substance in which particles are limited to vibration or rotation only and have a fixed volume and shape
