| Matter | anything that takes up space and has inertia |
| Inertia | resistance to change |
| heterogeneous mixture | can be separated by normal means |
| homogeneous mixture | evenly spread throughout and cannot be separated |
| physical property | does not change the identity of the substance |
| chemical property | does change the identity of the substance |
| solid | state of matter with definite shape and definite volume |
| liquid | state of matter with definite volume and takes the shape of the container |
| gas | state of matter with no definite shape and no definite volume |
| plasma | state of matter in very extreme condition like high heat and pressure |
| gravity | the force of attraction on an object |
| mass | the quantity or amount of matter present usually measured in grams |
| weight | the gravitational pull on an object |
| density | the amount of mass divided by the volume it occupies |
| volume | length x width x height |
| D=mass/volume | formula for density |
| g/mL | unit for density |
| g/cubic centimeter | unit for density |
| chemical change | chemical reaction or change in the identity of the substance |
| physical change | change in state or phase change |
