How will you separate sand and water from their mixture?
Share
To separate sand and water from their mixture, we follow the following steps:
• Leave mixture to stand undisturbed for some time in a container.
• Sand settles at the bottom of the container. It is called sedimentation.
• Gently pour the water in another container (called decantation).
• We may also use filter paper to remove fine particles of sand (called filtration)

1. Filtration: Pour the sand-water mixture through a filter to separate sand particles from water.
2. Collect Water: The filtered water passes through, separate from the sand.
3. Evaporation: Heat the collected water to evaporate it, leaving behind sand.
4. Collection of Sand: Once the water evaporates, collect and store the separated sand.
