- 3. The point at which a solid turns into a liquid.
- 5. Solid to gas (Example: dry ice)
- 7. A measure of hotness or coldness of something measured on a definite scale.
- 9. A very hot gas with an electrical charge. Has a lot more energy than the other 3 states of matter.
- 11. A device used to measure temperature.
- 14. A state of matter with no definite volume and no definite shape; particles are far apart and move quickly.
- 16. The temperature at which a liquid turns into a solid. (o degrees celsius / 32 degrees fahrenheit)

- 13. A state of matter with a fixed shape and volume; particles tightly packed and vibrate.
- 15. Gas to solid (Example: snow forming in clouds, frost)
- 17. A state of matter with a definite volume but no definite shape; particles close but can slide past each other.
- 19. The transfer of thermal energy; to heat something thermal energy is added.
