| Solute | Substances that dissolve into a solution |
| Solcent | Substance that dissolves solutes |
| Concentration | The amount of solute dissolved in a certain amount of solvent |
| Unsaturated Solution | A solution the more solute can be dissolved into a the current temperature |
| Saturated Solution | Solution that no more solute can be dissolved into at the current temperature |
| Solubility | The ability to dissolve. How much solute can dissolve into a specific amount of solvent |
| Saturation point | The point where no more solute can be dissolved into the solvent at the given temperature |
| Aqueous Solution | Solution where water is the solvent |
| Thermal pollution | When people take cool water out of a lake or pond and put back in warm water |
| Viscosity | The amount of resistance a fluid has to flow |
| Density | Measures the mass per volume. How much matter is in a given volume. |

| Matter | Anything that has mass and takes up space |
| Pure substances | Substances that are made up of only one type of matter. They can't be separated into different substances |
| Mixtures | Made up of different substances. Can be separated into different substances |
| Mechanical (heterogeneous) mixtures | Mixtures where the individual substances can be see |
| Suspensions | Mixtures in which droplets of one substance are held in another substance. Undisturbed, it's parts will usually separate |
| Colloids | Mixtures in which droplets of one substance are held in another substance except the drops are so small the mixture will not usually separate easily. It looks like one substance to the naked eye. |
| Solutions (homogeneous mixture) | Mixtures of two or more substances in which the individual substances can't be seen. Solutions look like pure substances even under a microscope. |
| Pressure | The measure of the amount of force applied to a certain area |
