Classifying Matter Vocab Review

2. Matter that is made up of only one type of atom
3. Matter that always has the same properties from sample to sample
6. State of matter whose atoms can flow from place to place. Definite volume, indefinite shape
7. Physical or chemical change where the system releases energy to its surroundings
8. Type of heterogeneous mixture where the particles do not mix together at all (large particles)
10. Matter that is combined in a NON-fixed ratio
12. Force applied over a unit of surface area
13. Phase change from a solid to a gas
14. Type of homogeneous mixture where a substance completely dissolves and cannot be seen (small particles)
19. Physical or chemical change where the system absorbs energy from its surroundings
21. Resistance of a liquid to flow
25. Type of heterogeneous mixture where the particles will settle to the bottom over time (medium particles)
26. Phase change from a liquid to a gas
28. Phase change from a gas to a solid
29. Ability of a substance to burn in the presence of oxygen

1. How readily a substance will chemically combine with another substance
4. Point at which all three states of matter can exist simultaneously
5. Type of mixture that looks uniform/all the same
9. Ability of a substance to allow heat or electricity to flow through it
11. Type of mixture where all of the individual parts look different
15. Phase change from a gas to a liquid
16. Phase change from a liquid to a solid
17. Phase change from a solid to a liquid
18. Measure of how acidic or basic a substance is
20. How bendable or flexible a substance is
22. Matter that is combined in a fixed ratio
23. Resistance of a substance to scratching/damage
24. Mass of a substance per unit of volume
25. State of matter whose atoms just vibrate in place. Definite shape and definite volume (lowest energy)
27. State of matter whose atoms have enough energy to fly off wherever they wish. Indefinite shape and indefinite volume (highest energy)
