| Matter | anything that occupies space and has mass; What all material consist of |
| density | how much mass there is in matter; amount of matter given in a space |
| liquid | matter with definite volume |
| melting point | solid to liquid; 1 C, 33F |
| condensation | when gas changes to liquid |
| boiling point | liquid to gas; 100 C, 212F |
| weight | force of gravity of an object |
| physical properties | color, shape, hardness |
| freezing point | liquid to solid; 0 C, 32 F |
| vaporization | molecules that gain energy with heat; liquid to gas |
| phases of matter | physical state of matter |
| chemical change | changes to new substance |
| melting point of water | above 0C degress |
| physical change | change from one phase to another |
| mass | amount of matter in an object |
| baking soda | a base |
| melting | when solid changes a base |
| volume | way to measure liquid; amount of space matter occupies |
| flammability, sharpening pencil, fireworks | chemical |
| reacts, ,apple turns brown | chemical change |
| ice melting, boiling water | physical |
| four phases of matter and characteristics | plasma, solid, liquid, gas |
| liquid | loosely packed - its volume is fixed |
| solid | molecules packed tightly |
| gas | molecules that are furthest apart, don't have fixed volume or shape |
