Threshers are used by farmers to separate the grains from the stalks or husks. The process, called threshing, involves beating the harvested crops to remove the edible part of the grain. Threshers make this process faster and more efficient compared ...
Buttermilk is separated from cream using the method of churning. In this process, cream (which is the fatty part of milk) is stirred vigorously in a churner. As the churning continues, the fat in the cream separates to form butter, ...
Salt is obtained from lakes like Sambhar Lake through the process of evaporation. The water from the lake is allowed to evaporate under the sun, leaving behind the salt. As the water evaporates, the salt gets concentrated and forms crystals. ...
The main property used in magnetic separation is magnetism. Magnetic materials, such as iron and steel, are attracted to a magnet, while non-magnetic materials, like sand or soil, are not. This property allows magnetic substances to be separated from non-magnetic ...
Sieving is used before making wheat flour dishes to remove any impurities or larger particles, such as husk or stones, from the flour. It also helps to aerate the flour, making it finer and smoother. This ensures that the dough ...
No, saltwater cannot be filtered to obtain salt because salt is dissolved in water and cannot be separated by filtration. Instead, the process of evaporation is used. When saltwater is heated, the water evaporates, leaving the salt behind as crystals. ...
During sedimentation, heavier solid particles in a liquid settle at the bottom of the container due to gravity. This process helps separate the solid particles from the liquid. After sedimentation, decantation is used to carefully pour off the clear liquid ...
In rural areas, a piece of cloth is often used as a filter because it is easily available and cost-effective. The cloth helps to separate solid particles, like dirt or impurities, from liquids, such as water. When water is poured ...
To separate chalk powder from water, the method of filtration is used. When chalk powder is mixed with water, it forms a suspension. By using filter paper, the water passes through, while the chalk powder gets trapped in the paper. ...
