| Term | Definition |
|---|---|
| matter | anything that has mass and volume |
| property | characteristic |
| intensive | not affected by the amount of the substance |
| hardness | the quality of being hard (int. and physical) |
| state | whether it's a solid (s), liquid (l), or gas (g) (int. physical) |
| color | The pigment it is (int. physical) |
| malleability | if you can bend it; it flexibility (int. physical) |
| density | m/v its a # but its intensive and physical |
| temperature | it's a # but it's intensive and physical |
| extensive | affected by the amount of the substance |
| volume | ext and physical m/d |
| mass | it's weight w/o gravity affecting it (ext physical) |
| perimeter | it's surrounding (ext physical) |
| circumference | area of a circle (ext physical) |
| physical properties | can be observed and measured w/o changing the composition (chem formula) of matter, can be intensive or extensive |
| chemical properties | properties that can be observed only when substances interact w/ each other; changes, all intensive |
| flammability | does it react with fire (int, chem) |
| rust formation | oxidation (int. chem) |
| rotten food | int. chem. |
| combustible | blow something up (int. chem.) |
| reacts with acid or base or litmus paper | int. chem. |
| evidence that chem reaction happened | new product; gas is produced, formation of a solid, heat or light is given off, change in color. |
| solid | definite shape, definite volume, definite mass, high density, not compressible vibrate |
| liquid | indefinite shape, definite volume, high density, not compressible, definite mass slide past one another |
| gas | indefinite shape, indefinite volume, very low density 1000X lower than solids/liquids, compressible, definite mass moves freely |
| sublimation | solid to gas (endothermic) |
| melting (fusion) | solid to liquid (endothermic) |
| vaporization | liquid to gas (endothermic) |
| condensation | gas to liquid (exothermic) |
| freezing (solidification) | liquid to solid (exothermic) |
| deposition | gas to solid (exothermic) |
| energy | increases as it goes from solid to liquid to gas |
