| matter | anything that has mass and takes up space |
| solution | has a uniform and constant composition, must be chemically broken down, |
| physical property | anything that can be observed or measured without changing the compostition (density, color, odor) |
| extensive properties | depends on the amount you have (mass length and volume) |
| intensive properties | does not depend on the amount of the substance (color, odor, density, hardness) |
| chemical properties | a substance changes as a result of combining with another substance |
| solid | a definite shape |
| liquid | assumes the shape of the container but has constant volume |
| gas | conforms to the shape of the container and always fills the entire volume of a container |
| vapor | the gaseous state of a liquid (liquid at room temperature) |
| physical change | any change that does not alter the makeup of the substance |
| chemical change | chemical reaction a change in the makeup of the substance making a new substance with its own unique properties |
| conservation of mass | law of conservation of mass- mass cannot be created or destroyed |
| mixture | combination of two or more pure substances each substance retains its own properties |
| heterogeneous | individual substances are still distinct |
| homogeneous | you do not see the parts it is a uniform composition |
| filtration | separtates solids and liquids |
| distillation | boils it |
| crystillization | evaporates liquids to crystilize the thing in the water |
| chromatography | -------------- |
| element | a substance that cannot be composed by any chemical reaction into simpler substances |
| compound | a substance chemically combining 2 elements |
| law of definite proportions | a compund alwaus contains a constant proportion of elements |
