Across
- 3. what we can see and measure without it turning into something else
- 8. the particles are close together
- 11. matter is made up of extremely tiny particles
- 13. amount of matter in a substaince
- 14. is the temperature which a liquid changes to a gas
- 16. the temperature at which a solid becomes a liquid
- 17. pure substaince made up of only one atom
- 21. energy of a motion or moving object
- 22. the particles are close together but they can move
Down
- 1. when gas turns to liquid
- 2. what a substaince does in a chemical reaction eg bubbling
- 4. when matter goes from solid to a gas without going to a liquid
- 5. all objects do this when heated
- 6. liquid changes to a gas
- 7. spontaneous spreading out of a substaince
- 9. occurs fastest in gases
- 10. how much space an object takes up
- 12. a solid changes to a liquid
- 15. the particles are far apart and move quickly
- 18. anything that has mass or volume
- 19. explanation of a small part of the natural world backed up by a lot of proof
- 20. when heat is removed from liquid
