| matter | anything that has mass and occupies space |
| mass | measure of the quantity of matter |
| element | substance that cannot be broken down into other substances by ordinary chemical change |
| compound | substance made up of two or more elements that ae chemically combined |
| mixture | combination of two or more substances in which each substance retains its individual properties |
| homogeneous mixture | mixture with uniform characteristics throughout |
| heterogeneous mixture | mixture with portions that have different characteristics or composition |
| properties | set of characteristics that can be used to recognize a substance |
| extensive properties | depend on the amount of the substance that is present (volume, weight, mass, length) |
| intensive properties | properties that do not depent on the amount of substance resent (melting point, boiling point) |
| density | measure of the quantity of mass of a substance that occupies one unit of volume |

| conductivity | physical property describing metals ability to conduct (carry) electrical charges |
| chemical properties | characteristics describing how substances interact in the presence of other substances to produce new substances |
| physical change | change in physical properties o a substance without a change in chemical properites or composition |
| chemical change | change resulting in the production of substances that differ in chemical properties and composition from the original substance |
| miscible | describes two liquids that can mix together to from a solution |
| immiscible | describes two liquids that when mixed form a heterogeneous mixture |
