What is the process of threshing?
Threshing is the process in which stalks (such as stalks of wheat, paddy , etc.) are beaten to separate grains from the stalks and from the chaff that covers the grains. The separation method is based on the fact that crop plant stalks and chaff are soft materials, whereas grains are extremely hard. Because stalk and chaff are soft, they can be broken into pieces when beaten, but the grains are unaffected.
How is insoluble solid separated into clear liquid?
The insoluble solid mixture and the liquid are poured into a filter paper cone fixed in a funnel by using a glass rod as a guide. The liquid flows through the filter paper and collects in the beaker beneath the funnel. Solid particles do not pass through the filter paper and remain on it. The solid substance left behind on the filter paper is called the residue. The clear liquid obtained is called the filtrate. In this way, a mixture of insoluble solid in a liquid is separated into the solid and clear liquid.

Fractional crystallization is used to separate more salts based on the difference in their solubilities The solubilities of different salts in a given solvent must differ at different temperatures. During the cooling process, at a particular temperature, crystals of salts start forming as cooling continues.

Crystallization is a method used to separate salts that decompose easily on heating from their solutions. The salt solution is first heated to evaporate some of the solvents, the solution then becomes saturated. When the saturated solution is cooled, crystals of the salt begin to form. The salts are obtained purely as crystals containing water of crystallization.

What is separation process?
A separation process or technique is a method that converts a mixture or solution of chemical substances into two or more distinct product mixtures. At least one of results of the separation is enriched in one or more of the source mixture’s constituents. In some cases, a separation may fully divide the mixture into pure constituents. Separations exploit differences in chemical properties or physical properties (such as size, shape, mass, density, or chemical affinity) between the constituents of a mixture.

Hand-Picking
- Hand-picking means taking out by hands. Hand-picking is a method of manually separating small substances visible to the naked eye from a mixture. It is used to separate substances that differ in size, shape, or colour and that can be picked up by hand because they are typically present in small quantities.

Winnowing
- Winnowing is the method of separating heavier and lighter components of a mixture with the help of wind or blowing air. In this process, a mixture of grain and husk is made to fall from a height with the wind blowing over it. The husk, being lighter, blows away and forms a heap some distance away. The heavier grains fall to the ground and form a separate heap. Practice Exam Q…
Applications of Winnowing
- The winnowing method is used to separate the husk from various types of grains like wheat, rice, etc.
- Winnowing can be used to separate sand from sawdust or sand from dried leaves. Sawdust and dried leaves being lighter get blown away by wind and form a separate heap at a distance.
Applications of Sieving
- The flour that we get from the flour mill has some bran mixed in a fine flour. Sieving is used to separate the bran from fine flour.
- We require fine sand to be mixed with cement before plastering the walls of a house. The sieving method is used to obtain fine sand.
Magnetic Separation
- Magnetic separation means ‘separation of a mixture by using a magnet’. We know that a magnet attracts iron. This property of iron is used to separate it from a mixture. For example, a magnet can be used to separate a mixture of iron filling and sulphur powder. This is because iron filings are magnetically attracted, whereas sulphur powder is not.
Evaporation
- The changing of a liquid into vapour is called evaporation. Evaporation is used to obtain a solid substance that has dissolved in water. Although evaporation takes place at room temperature, it is much faster when the water is heated. When the mixture is heated till all the water evaporates in the air, only the dissolved substance is left behind as a solid residue. For example, The comm…
