| solid | the state of matter in which a substance has a definite shape and a definite volume |
| liquid | the state of matter in which a substance has a definite volume, but no definite shape |
| gas | the state of matter in which a substance has neither a definite shape nor a definite volume |
| sublimation | the process of chang¬ing from solid to gas without going through the liquid state |
| condensation | the process of changing from gas to liquid |
| vaporization | the process of changing from liquid to gas |
| fusion | the process of changing from solid to liquid |
| solidification | changing from liquid to a solid |
| mixture | a combination of two or more pure substances such as that each one's properties are not lost, but may be hidden |
| Pure Substance | a material that contains only one kind of particle |
| Element | pure substance with nly 1 type of particle |
| Compound | pure substance with 2 or more elements combined chemically |
| Homogeneous | the same in structure, quality, or kind |
| Heterogeneous | made up of parts, or mixed |
| Mechanical Mixture | mixtures that are obviously heterogeneous |
| Solution | homogeneous mixture in which no settling occurs |
| Suspension | a heterogeneous mix¬ture in which particles settle slowly after mixing |
| Colloid | a heterogeneous mixture in which particles do not settle |
| Emulsion | a mixture in which droplets of fat are prevented from joining together by an emulsifying agent |
| Phases | separate parts of a mechan¬ical mixture |
| Dissolving | breaking up; forming |
| Solute | a substance that dissolves |
| Solvent | a substance that dissolves a solute to form a solution |
| Soluble | able to be dissolved in a particular solvent |
| Rate of Dissolving | how fast a solute dissolves in a solvent |
| Insoluble | not able to be dissolved in a particular solvent |
| Agitation | stirring or shaking |
| Solubility | solubility the mass of a solute that can dissolve in a given amount of solvent (100mL) to form a saturated solution at a given temperature |
| Saturated Solution | a solution in which no more solute will dissolve in a specific amount of solvent at a specific temperature |
| Unsaturated Solution | a solution in more solute has been dissolved |
| Supersaturated Solution | a solution that contains more solute than would normally dissolve at a certain temperature |
| Concentration | the amount of solute dissolved in 1 mL of solvent |
