Across
  1. 1. The energy stored in objects that are up high
  2. 3. Generated by vibrations, can be loud or quiet
  3. 6. what all matter is made of
  4. 9. The energy stored in food, fuels, and chemicals
  5. 10. Particles have lots of kinetic energy and are widely spaced out, no bonds
  6. 11. When a solid is heated and becomes a liquid
  7. 13. The energy stored in objects that can be stretched or squashed
  8. 15. Heat transfer through solids; Heated particles vibrate and bump into neighboring particles
  9. 16. Occurs when heated particles vibrate more and spread out } the object gets bigger
  10. 18. Heat energy stored in the environment
  11. 23. Heat transfer through liquids and gases; Heated particles rise due to low density, and sink due to high density
  12. 24. When a liquid is cooled and becomes a solid
  13. 25. particles arranged close together in rows, strong bonds
Down
  1. 2. Heat emitted by all warm/hot objects in waves; does not require particles
  2. 4. When a liquid is heated and becomes a gas
  3. 5. Energy can never be created or destroyed, but can transform from one form to another
  4. 7. When a solid is heated and becomes a gas, without first becoming a liquid
  5. 8. The energy in all moving objects (including particles)
  6. 12. The energy that travels in electromagnetic waves, allows us to see
  7. 14. Occurs when particles are cooled and move closer together} the object gets smaller
  8. 17. The transfer of energy between objects, due to a difference in their temperatures
  9. 19. particles mostly touching, weak bonds, particles not in rows
  10. 20. The energy carried by electrons in electrical circuits
  11. 21. When a gas is cooled and becomes a liquid
  12. 22. The ability to do work, needed to 'make things happen'; measured in Joules
