Separation of substances
1. Methods of separating substances: Methods of separating substances are handpicking, winnowing, sieving, sedimentation, decantation and filtration.
2. Husk and stones: Husk and stones could be separated from grains by handpicking.
3. Solid dissolved: Evaporation can be used to separate a solid dissolved in a liquid.
4. Dissolved: A saturated solution in one which no more of that substance can be dissolved.
5. Dissolved: A saturated solution in one which more of that substance can be dissolved.
6. Separation: separation methods is used to remove or picked out unwanted substances from mixtures.
7. Dissolving a substance: A solution is separated by dissolving a substance in a liquid.
8. Fodder for cattle: The separated husk is used for many purposes such as fodder for cattle.
9. Husk particles: Winnowing is commonly used by separate lighter husk particles from heavier seeds of grains.
10. Mixtures: Things are made of two and more of two substances are called mixture. Like air, particular dust, sherbet etc.
11. Separation: By various methods a mixture is separated into its separates components are known as separation.
12. Sedimentation: The settling down of heavy solid particles from the liquid in mixtures of solid and liquid substances.
13. Filtration: It is a method of separating specific particles from a liquid mixture by passing through a porous membrane.
14. Decantation: The process of separating a solid from a liquid by out the liquid.

20. Separated from muddy water: Sedimentation and loading are separated from muddy water.
21. Separated the iron: Magnetic separation is separated the iron.
22. Separated the sieves/ sieving method: substances of two solid of different size can be separated the sieves/ sieving method like flour.
23. Saturated solution: The solution in which no more substances can be dissolved in the amounts of water we have taken.
24. Separated husk of wheat grains: Separated husk of wheat grains is used for many purposes such as fodder for cattles.
25. Winnowing success: The wind makes the winnowing success.
