- 5. A change of state from a gas to a liquid
- 11. The physical forms that matter can exist in.
- 13. The transfer of heat energy in the form of waves
- 14. The change in state from a solid to a liquid

Down
- 1. Occurs when there is a difference in temperature between two parts of a liquid or gas
- 2. A change of state from a liquid to a gas
- 3. A change of state from a solid directly to a gas
- 4. A change of state from a gas directly to a solid
- 6. Anything that has mass and takes up space. Makes up everything in the universe.
- 7. The energy that comes from heat. This heat is generated by the movement of tiny particles within an object. The faster these particles move, the more heat is generated.
- 8. A physical change that occurs when matter changes from one state to another.
- 9. Small particles found in all matter.
- 10. The temperature at which a liquid turns into a gas
- 12. The change of state from a liquid to a solid
- 17. A state of matter that is like a superheated gas. Can be found in lightning, flames, and the Northern Lights.
- 18. A state of matter that has a definite volume, but does not have a definite shape.
- 21. A state of matter with no definite shape or volume.
