Explanation
Milk is a colloidal system classified as an emulsion. An emulsion is a mixture where both the dispersed phase and the dispersion medium are liquids. In milk, liquid fat globules (dispersed phase) are distributed throughout water (dispersion medium). This mixture is stabilized by proteins like casein, which act as emulsifiers.
Other types of colloids mentioned include:
- Foam: Gas dispersed in a liquid (e.g., whipped cream).
- Sol: Solid dispersed in a liquid (e.g., paint or ink).
- Aerosol: Liquid or solid dispersed in a gas (e.g., fog or smoke).
