Across
- 1. idea that molecules are in constant motion
- 3. when two or more pure substances are together but not chemically combined
- 7. random movement of molecules, how heat and gases spread
- 8. a substance that cannot be broken down
- 9. made up of two or more elements bonded together
- 13. phase change where liquids become a gas
- 14. phase change that decreases energy between plasma and gas
- 17. phase change that increases energy in a gas
- 18. phase change that decreases energy between liquids and solids
- 20. ionized gas that emits electrons
- 21. phase change that increases energy and causes solids to become liquid
- 24. type of system that allows energy to move but mass can not move in or out
- 25. states that matter can not be created nor destroyed
Down
- 2. type of property that changes with the amount of the object, like volume for example
- 4. phase change that goes straight from a solid to a gas, skipping liquid
- 5. phase change where gases become liquid, like water vapor in clouds
- 6. type of property that doesn't change with the amount of the object that you have, like color for example
- 10. type of system that allows both energy and mass to move in and out
- 11. anything that has mass and takes up space
- 12. mixtures with the same molecules throughout that appear uniform throughout
- 15. state of matter that has a geometric pattern within its molecules
- 16. mixture with two or more compounds that can be distinguished
- 19. state of matter that does not have bonds
- 22. state of matter that has a fixed volume but not a fixed shape
- 23. type of property that can be observed without changing the identity of a substance
