Question

Which of the following devices uses the principle of centrifugation?

• A. Washing machine
• B. Ceramic water filter
• C. Household ultraviolet (UV) purifier
• D. Distillation tower

Answer 1

The correct option is A Washing machine

Centrifugation is a technique that involves the application of centrifugal force to separate particles from a solution according to their size, shape, density, the viscosity of the medium, and rotor speed. The larger the size and the larger the density of the particles, the faster they separate from the mixture. For example- the washing machine works on the principle of centrifugation.

Hence, option $A$ is correct.
