Process used to separate insoluble particles from liquids is ___________ ?
Correct answer: B. Filtration
- A. Drying
- B. Filtration
- C. Sieving
- D. Extraction
Explanation
Filtration separates an insoluble solid from a liquid by passing the mixture through a porous medium that retains the solid particles. Sieving is the likely alternative choice, but it separates solid particles of different sizes and is not normally used for a solid-liquid suspension.

About Properties of Liquids
Liquid behavior depends on intermolecular forces, which produce surface tension, viscosity, capillary action and a definite volume without a fixed shape. The topic also covers vapor pressure, evaporation, boiling point and the effect of temperature and external pressure, while distinguishing evaporation at the surface from boiling throughout the liquid.
