- 4. Transfer of heat through a solid object from a source of higher temperature to the object with lower temperature.
- 7. The ___ energy in a battery converted to electrical energy is an example of energy conversion.
- 8. When a liquid becomes a solid; molecules become packed tighter together and move less.
- 9. An example of a chemical property is when copper ___ or iron rusts.
- 12. ___ waves are all waves of energy including visible light, microwaves, infrared, x-rays, & radio waves.
- 15. A Physical Change does not ___ any new substance.
- 18. Heat transferred by electromagnetic waves.
- 20. The rubbing of one object or surface against another.
- 21. ___ potential energy equals “mass times gravity times height”.
- 23. 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.
- 25. Occurs when a solid changes to a liquid allowing molecules to move more freely.
- 26. ___ properties include things like an object’s color and density
- 28. 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)”.
Down
- 1. The energy of motion (the energy an object has because it is moving).
- 2. A reaction/interaction that gives off heat (feels warm/hot to touch).
- 3. Newton’s Second Law of Motion also says “Force equals mass times ___”.
- 5. Transfer of heat by liquid or gas.
- 6. Newton’s ___ Law of Motion says “For every action there is an equal & opposite reaction”.
- 10. Friction causes an object to slow down or ___.
- 11. When clouds can no longer hold all the water from condensation they will release the water in the form of rain or snow.
- 13. When a liquid becomes a gas; the molecules are now moving very rapidly.
- 14. A reaction/interaction that absorbs heat from the surrounding (feels cold to touch).
- 16. This force will accelerate all objects.
- 17. Kinetic energy equals “___ times velocity squared”.
- 19. Stored energy or the ability of a system to do work due to its position or internal structure.

- 24. When ice goes directly into gas form skipping becoming a liquid phase.
- 26. A Chemical Change ___ a new substance.
- 27. Newton’s ___ Law of Motion says “A force causes an object to accelerate”.
