| Question | Answer |
|---|---|
| Anything that has a mass and a volume. | matter |
| The building blocks of matter; made up of protons, electrons, and neutrons. | atoms |
| Two or more atoms are joined together chemically. Elements can be different or the same. Example: O + O = O2 | molecules |
| A molecule that has two or more different elements bonded together. Example: H + O = H2O | compound |
| Parts do not combine. Each keeps its own properties. Can be separated. Example: sand in water. | heterogeneous mixture |
| Uniform distribution. Example: sugar in water | homogeneous mixture |
| Groups of molecules that are mixed in a completely even distribution. A solute dissolved in a solvent. | solution |
| The substance to be dissolved. Example: sugar. | solute |
| The one doing the dissolving. Water is a universal one | solvent |
| No chemical change. Each keeps its own properties. Can be separated. | mixture |

| Process in which the parts of a substance or liquid mixture are separated by heating it to a certain temperature and then condensing the resulting vapors | distillation |
| A method of separating a mixture where the liquid turns into a gas and the solid residue is left behind | evaporation |
| A method of separating a mixture by removing metals from non-metal substances | magnetism |
| A method of separating a mixture that uses a screen-like device or mesh device to separate larger objects from smaller objects | sifting |
| Atoms are held together by a force of attraction | bonded |
| A pure substance that is the building block of all matter | element |
| A substance made from a single type of atom or one type of molecule; can be a compound or a single element; Examples: diamonds, salt, gold | pure substance |
