1. A washing machine works by spinning the clothes at high speed.
2. This spinning action generates a centrifugal force that pushes water out of the clothes through the small holes in the drum.
3. This process of separating substances based on density using centrifugal force is called centrifugation.
4. Dialysis is used for blood purification.
5. Reverse osmosis is used for water purification.
6. Diffusion is the movement of particles from higher to lower concentration.
