What are separation technique plus physical property used for separation of sand and water
Accepted Answer
Separation techniques and physical properties used for the separation of sand and water:
1. Filtration: This technique uses a filter paper or a filter cloth to separate sand from water. The filter paper allows water to pass through, while the sand particles are trapped on the filter.
2. Decantation: This technique is based on the difference in density between sand and water. The mixture is allowed to settle, and the sand particles sink to the bottom of the container. The water can then be carefully decanted or poured off from the top.
3. Centrifugation: This technique uses a centrifuge to separate sand from water. The mixture is placed in a centrifuge tube and spun at high speed. The sand particles are forced to the bottom of the tube by the centrifugal force, and the water can be decanted off from the top.
Physical properties used to separate sand and water:
1. Size: Sand particles are larger than water molecules, so they can be separated by filtration or sieving.
2. Density: Sand particles are denser than water, so they can be separated by decantation or centrifugation.
