Across
  1. 3. Transfer of heat by liquid or gas.
  2. 6. ___ properties include things like an object’s color and density
  3. 8. The ___ energy in a battery converted to electrical energy is an example of energy conversion.
  4. 12. When a liquid becomes a solid; molecules become packed tighter together and move less.
  5. 13. ___ potential energy equals “mass times gravity times height”.
  6. 15. Newton’s ___ Law of Motion says “For every action there is an equal & opposite reaction”.
  7. 17. An example of a chemical property is when copper ___ or iron rusts.
  8. 19. When clouds can no longer hold all the water from condensation they will release the water in the form of rain or snow.
  9. 21. When a liquid becomes a gas; the molecules are now moving very rapidly.
  10. 23. The energy of motion (the energy an object has because it is moving).
  11. 24. A Physical Change does not ___ any new substance.
  12. 25. Newton’s ___ Law of Motions says “a body at rest remains at rest and a body in motion remains in motion until an outside force acts on it (inertia)”.
  13. 27. The Law of conservation of Energy says “___ energy cannot be created or destroyed only converted to another type of energy”.
Down
  1. 1. Stored energy or the ability of a system to do work due to its position or internal structure.
  2. 2. Occurs when a solid changes to a liquid allowing molecules to move more freely.
  3. 3. When a gas becomes a liquid. This occurs on a cold glass beverage on a warm day and this is also how clouds are formed.
  4. 4. ___ waves are all waves of energy including visible light, microwaves, infrared, x-rays, & radio waves.
  5. 5. When ice goes directly into gas form skipping becoming a liquid phase.

  10. 14. Newton’s Second Law of Motion also says “Force equals mass times ___”.
  11. 16. A reaction/interaction that gives off heat (feels warm/hot to touch).
  12. 18. Newton’s ___ Law of Motion says “A force causes an object to accelerate”.
  13. 19. A Chemical Change ___ a new substance.
  14. 20. Transfer of heat through a solid object from a source of higher temperature to the object with lower temperature.
