Matter: Occupies volume and space, particles in constant motion, has mass. Separation techniques:
- Filtration
- Dissolution - Solubility
- Crystallization - Heat, cool down to turn into crystals
- Evaporation
- Distillation - Different boiling point
- Paper chromatography - attraction to mobile phase
Categorization
Matter can be sorted into two categories, each of which can be separated into two more categories. Pure: Element, compounds Mixture: Homo and heterogenous
States
| Solid | Liquid | Gas |
|---|---|---|
| High intermolecular forces, particles closely packed. Fixed shape and fixed volume. | Weaker intermolecular forces, particles more spaced. No fixed shape, but fixed volume. | Intermolecular forces negligible, no fixed shape or volume. |
