|---|
| sublimation | change of state from gas to solid or solid to gas |
| freezing | change of state from liquid to solid |
| melting | change of state from solid to liquid |
| condensation | change of state from gas to liquid |
| evaporation | change of state from liquid to gas |
| mechanical mixture | mixture of 2 or more substances in which you can see at least 2 of the substances (also known as a heterogeneous mixture) Eg. chocolate chip cookie |
| solution | mixture of 2 or more substances but the mixture looks like one substance (also known as a homogeneous substance) Eg: chocolate milk |
| soluble | a substance that dissolves in solvent at a given temperature |
| insolube | a substance that does not dissolve in a solvent at a given temperature |
| hydraulic system | uses fluids under pressure to move loads |
| WHMIS | Workplace Hazardous Materials Information System |
| Fluid | anything that has no fixed shape and can flow (usually a gas or liquid) |
| hydrometer | a device used to measure the density of liquid |
| pure substance | a substance made up of one type of particles Eg: table salt |
| matter | anything that has mass and occupies space |
| mixture | a combination of two or more substances |
| suspension | a cloudy mixture in which droplets or tiny pieces of one substance are held within another substance. If you leave a suspension undisturbed, its parts will usually separate. Eg: muddy water |
| colloid | cloudy mixture but the droplets or tiny pieces are so small that they do not separate out easily |
| paper chromatography | a test to determine if a substance is a pure substance or a solution |
| solute | The substance that is dissolved in a solution. Usually found in smaller quantities |
| solvent | The substance that does the dissolving in a solution. Usually found in larger quantities. |
| concentration | the amount of solute dissolved in a specific amount of solvent |
| diluted | very small amount of solute in comparison to the amount of solvent (weak kool-aid) |
| concentrated | large amount of solute in comparison to the amount of solvent (strong kool-aid) |
| saturated | when a solute cannot dissolve anymore solvent |
| solubility | maximum amount of solute you can add to a fixed volume of solvent at a given temperature |
| saturation point | occures when no more solute can be dissolved in a fixed volume of solvent at that temperature |
| aqueous solution | solvent is water |
