उत्तर
One criterion for classifying colloids is the physical state of the dispersed phase and dispersion medium. The type of dispersed phase and dispersion medium (solid, liquid, or gas) determines the eight types of colloidal systems.
| Dispersed phase | Dispersion medium | Type of colloid | Example |
| Solid | Solid | Solid Sol | Gemstone |
| Solid | Liquid | Sol | Paint |
| Solid | Gas | Aerosol | Smoke |
| Liquid | Solid | Gel | Cheese |
| Liquid | Liquid | Emulsion | Milk |
| Liquid | Gas | Aerosol | Fog |
| Gas | Solid | Solid foam | Pumice stone |
| Gas | Liquid | Foam | Shaving cream |
