| material w/ weight, mass, and occupies space | matter |
| solids to gasses | sublimation |
| gasses to solids | vapor deposition |
| solids to liquids | melting |
| liquids to gasses | evaporation |
| gasses to liquids | condensation |
| liquids to solids | freezing/solidification |
| two factors determine state of matter: | pressure and temp |
| what does matter consist of? | elements, molecules, and compounds |
| What is the primary characteristic of life, according to this Prof? | Metabolism, as in living things carry out processes |
