Question | Answer |
a quality of a substance that never changes and can be used to identify that substance | Characteristic Property |
the temperature at which a substance changes from a liquid to a gas | boiling point |
the temperature at which a substance changes from a solid to a liquid | melting point |
a change in a substance that does NOT change its identity | physical change |
a change in which one or more substances combine or break apart to form new substances | chemical change |
this indicates a substance's ability to undergo a chemical change | chemical activity |
two or more substances that are mixed together but not chemically combined | mixture |
a well-mixed mixture that contains at least one liquid | solution |
a substance made of only one type of matter and having definite properties | pure substance |
a substance that cannot be broken down into other substances by chemical or physical means | element |
a substance made of two or more elements that are chemically combined | compound |
Which of the following IS NOT an example of a characteristic property? melting point, density, volume, chemical activity, hardness | Volume |
Which of the following IS NOT a pure substance? water, air, gold, salt, iron | air |

True or False... Earth, air, fire and water are good examples of (chemical) elements. | FALSE!!!! |
Which of the following classifications should include water: pure substance, mixture, element, compound | pure substance and compound |
What are the characteristics of a mixture? | -Two or more pure substances blended together -relatively easy to separate -usually solids and gases -not chemically combined |
What are the characteristics of a solution? | -a very well-mixed mixture -contains at least one liquid -more difficult to separate -not chemically combined |
Are phase changes (solid to liquid or liquid to gas) physical or chemical changes? | physical changes |
Did you study your chemistry classification chart? | If you said "yes"... GREAT! If you said "no"... GO STUDY IT! |
