| A | B |
| solid | state of matter with definite shape and volume |
| liquid | state of matter with definite volume, but no definite shape |
| gas | state of matter with no definite shape or volume |
| chemical property | characteristic of matter that describe its ability to combine and change |
| physical property | characteristic that can be observed without changing matter |
| intensive property | characteristic that is the same regardless of sample size (color, temperature, etc.) |
| extensive property | characteristic that depends on sample size (mass, volume, etc.) |
| plasma | fourth, high energy state of matter most often found in stars |
| vapor | gas form of something that is usually a liquid or solid at room temperature |
| chemical change | change that fundamentally alters a sample, like burning |
| physical change | change that is reversible, like freezing or boiling |
| phase change | change from one state of matter to another |
| chromatography | separating or identifying parts of a chemical by spreading them out on another material |
| filtration | using a porous barrier to separate liquids from solids |
| distillation | separation technique based on boiling points |
| crystallization | separation technique where a solid is forced out of a solution |
| sublimation | transition from solid directly to a gas |
| solution | best mixed mixture, extremely hard to tell there are different parts; ex: sugar water |
| mixture | two substances that are physically combined |
| compound | two or more elements chemically combined with one or more chemical bonds |
| element | basic form of matter; cannot be broken into simpler forms |
| homogeneous mixture | mixture that has an almost uniform composition |
| heterogeneous mixture | mixture where the parts are easily identifiable |
| law of definite proportions | the formula of a compound is always the same |
| law of multiple proportions | elements will form compounds with different formulas under different conditions |
| periodic table | arrangement of the known elements in systematic form |
| percent by mass | formula to find out what part of a compound or mixture is made of a certain piece of the whole |
