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