Unit 6 Matter

2. Properties that can only be observed or measured by changing the chemical identity of a substance (2nd word is Properties)
4. Two or more substances physically combined (variable composition)
7. A diagram that shows the state transitions a substance goes through as heat/energy is added to it
8. Two or more elements chemically combined in a fixed proportion
10. Measure of compactness or consistency of a material
12. Atoms that are super-cooled to such a low temperature (almost absolute zero) that they form a “super atom”
13. Fixed volume and fixed shape
14. Temperature at which a solid becomes a liquid
18. Substances in the mixture are not evenly spread out
20. The phase/state transition from liquid to gas
21. All particles in matter are identical (fixed composition)
23. A measure of how well a solute dissolves in a solvent
24. Matter is neither created or destroyed during a chemical change. It only changes forms (Law of ______________ of Matter)
25. Properties that can be observed directly or measured without chemical identity of the substance (2nd word is Properties)

1. Anything that takes up space and has mass
3. Temperature at which a liquid becomes a gas
5. Components are evenly distributed out on a microscopic level
6. The amount of energy needed to turn a solid into a liquid at its melting point
9. Matter composed of positively and negatively charged particles with extremely high kinetic energy
11. Fixed volume but shape changes based on container it is in
15. Caused by pressure change, occurs only at the surface of a liquid
16. No fixed volume or shape
17. Caused by a temperature change, occurs throughout the liquid
19. Simplest form of matter from which more complex substances are made (listed on the Periodic Table)
22. A fluid’s resistance to flow
