| what is matter | the study of the composition,k structure, and properties of matter and the changes that matter undergo |
| what is mass | a measure of an amount of matter |
| what is volume | a measure of an amount of space |
| how does the composition of a pure compound differ from a mixture | the proportions of elements in a pure compound are found |
| define property | any characteristics of a substance or material |
| how are properties useful in classifying materials | members of known groups or subgroups of substances or for identifying substances directly |
| what is the difference between extensive and intensive properties | extensive properties depend on the amount of matter that is preset and intensive properties don't |
| define chemical property | a property that describes a substance's ability to undergo changes that alter its identity |
| list two examples of chemical properties | the ability of coal to burn and tghr ability of iron to rust |
| distinguish the difference between a chemical changes and a physical change | a physical change doesn't include a change in a substance's identity, a chemical change converts one substance into other substances |
| how does a solid differ from a liquid | a solid has a define volume and a definite shape, a liquid has a definite volume but takes the shape of its container |

| how is a liquid similar to a gas | liquids and gases take the shape of the container |
| what is meant by the change in state | a change of substance from one state of matter to another |
| suppose different parts of sample material have different compositions, what can you conclude about the material | it must be a mixture |
| define physical property | a property that can be observed or measured without changing the identity of the substance |
| list two examples of physical properties | color, odor, length, size, and melting point |
| how can you tell the difference between an element and a compound | compounds can be separated into elements by chemical means, elements can't be separated into simpler substances by chemical means |
| is a piece of wood sawed in half physical or chemical change | physical because the wood remains wood |
