| PURE SUBSTANCE | TYPE OF MATTER WITH FIXED COMPOSITION |
| ELEMENT | MADE UP OF ATOMS THAT ARE ALL ALIKE |
| COMPOUND | 2 OR MORE ELEMENTS CHEMICALLY COMBINED IN A FIXED PROPORTION |
| HETEROGENOUS MIXTURE | EXAMPLE IS SALAD DRESSING |
| SUSPENSION | TYPE OF HETEROGENEOUS MIXTURE MADE OF LIQUIDS AND SOLID PARTICLES WHICH SETTLE OUT |
| COLLOID | HETEROGENEOUS MIXTURE WHERE PARTICLES DON'T SETTLE |
| HOMOGENEOUS MIXTURE | a solid, liquid, or gas that contains 2 or more substances blended evenly throughout. |
| SOLUTION | homogeneous mixture that remains constantly and uniformly mixed and has particles that are so small they cannot be seen with a microscope |
| TYNDAL EFFECT | result of scattering of a light beam as it passes through a colloid |
| HETEROGENEOUS MIXTURE | COMBINATION OF DIFFERENT MATERIALS IN WHICH THE COMPONENTS REMAIN DISTINCT |
| ELEMENT | a pure chemical substance that is made up of only one kind of atom |
| ATOM | a basic unit of matter that cannot be easily created nor destroyed |
| MOLECULE | the smallest natural occurring unit of a compound; has a definite shape and is determined by how atoms are bonded or combined with each other |
| MIXTURE | a substance formed by physical combination; composition can vary |
| distillation | the process that can separate two substances in a mixture by evaporating a liquid and recondensing its vapor |
| HETEROGENEOUS MIXTURE | A material made up of two or more substances that can easily be separated by physical means |
| TYNDAL EFFECT | scattering of a light beam as it passes through a colloid. |
| MIXTURE | Two or more substances that aren't chemically combined with each other and can be separated by physical means. Substances in this retain their original properties. |
| ATOM | The basic building block of matter. |
| SOLVENT | SUBSTANCE IN SOLUTION THAT DOES DISSOLVING |
| SOLUTE | SUBSTANCE IN SOLUTION THAT IS DISSOLVED |
| SATURATED SOLUTION | Maximum amount of solute dissolved in solvent |
| UNSATURATED SOLUTION | Less than maximum amount of solute dissolved in solvent |
| SUPERSATURATED SOLUTION | More than maximum amount of solute dissolved in solvent |
| DILUTE | to make a solution less concentrated |
| SEDIMENTATION | tendency for particles in suspension with a greater mass to settle out of the fluid in which they are entrained and come to rest against a barrier |
| FILTRATION | physical, biological or chemical operation that separates solid matter and fluid from a mixture with a filter medium that has a complex structure through which only the fluid can pass |
| DISTILLATION | physical process of separating the components or substances from a liquid mixture by using selective boiling and condensation. |
| DECANTATION | physical separation of a mixture where the layer closer to the top of the container—the less dense of the two liquids, or the liquid from which the precipitate or sediment has settled out—is poured off, leaving the other component or the more dense liquid of the mixture behind. |
| MOLECULE | FORMED AS A RESULT OF TWO OR MORE ATOMS BEING JOINED CHEMICALLY |
| HOMO | PREFIX FOR "SAME" |
| HETERO | PREFIX FOR "DIFFERENT" |
| chemical change | Iron and oxygen form rust. |
| chemcial property | wood will burn |
| physical property | properties can be observed or measured without changing the composition of matter. |
| physical change | salt dissolves in water |
| physical change | water is heated and changed to steam |
| chemical change | wood rotting |
| physical change | blue dye mixed with red dye make purple color |
| chemical change | 2 clear substances combine and form a cloudy substance |
| SUPERSATURATED | contains more than the average solvent that can be dissolved at a given temperature. |
| DILUTE | there is a relatively small amount of solute dissolved in the solution |
