Down
- 1. a mixture in which you can see the different parts and are more easy to separate
- 2. any type of matter (solid, liquid, gas, plasma) made of atoms that has a specific density (examples: brass, water, aluminum, pine, PVC, copper, nylon, hydrochloric acid, rust)
- 3. Mixture that is the same throughout. and are more difficult to separate
- 4. A technique that is used to separate the substances of a mixture based on the tendency of each component to travel up filter paper using water or another solvent
- 5. a separation technique that produces pure solid particles of a substance from a solution that contains the dissolved substance
- 7. process that can be used to evaporate a liquid from a mixture and leave the solid
- 8. anything that has mass (g) and takes up space (volume) - solid, liquid, gas, plasma
