Across
- 2. vibrates air molecules
- 4. stored energy
- 5. phase chane that goes from liquid to gas
- 7. holds atoms in molecules together
- 10. holds protons & neutrons together in the nucleus of atoms. This energy powers the sun and nuclear power plants.
- 11. movement of electrons through matter
- 12. point liquid turns into gas
- 13. the most common state of matter in the universe. Plasma occurs when matter is heated so much that the atoms begin to break apart.
- 15. point liquid turns into gas
- 18. vibration of particles within matter. The faster they vibrate the more heat energy they have
- 20. average energy of molecules
- 22. point at which a solid turns into a liquid
- 23. liquid turns into a solid
Down
- 1. energy changes from one form to anothe
- 2. definite size and shape. The particles which make it solid vibrate but do not change position.
- 3. Although energy changes form and is not lost
- 6. phase change that goes from liquid to gas
- 8. tiny particles that make up matter
- 9. energy of moving things
- 14. energy carried by light nucleus of atoms
- 16. always has a definite volume but not a definite shape. The molecules that make it up can move over & around each other, but do not separate from one another.
- 17. energy of motion
- 19. has no definite size or shape. The molecules that make it up can move freely & separately from one another.
- 21. ability to make things move
