उत्तर
Colloidal particles can be made to settle under high speed centrifugation.
Explanation:
Normally, colloidal particles do not settle down due to gravity because their size is very small, and they remain suspended due to Brownian motion. However, when subjected to high-speed centrifugation, the intense centrifugal force acts much stronger than gravity, causing the colloidal particles to sediment and settle. This process is commonly used to separate or purify colloidal dispersions by forcing the particles to come out of suspension through rapid spinning.
