1. Winnowing is used for (A) Separating heavier and lighter components. It is a process where wind or air is used to separate lighter husk particles from heavier grains. Farmers traditionally perform winnowing by dropping the mixture from a height, allowing the wind to blow away the lighter husk. For mRead more

  2. The correct method to separate bran from wheat flour is (B) Sieving. A sieve with fine mesh is used to allow the smaller flour particles to pass through while retaining the larger bran particles. This process helps in refining wheat flour for various uses.

  3. The correct method to separate oil from water is (C) Decantation. Since oil is less dense than water, it floats on top. By carefully pouring out the upper oil layer, it can be separated from water without mixing the two liquids. For more visit here: https://www.tiwariacademy.in/ncert-solutions/classRead more

  4. The correct answer is (C) To allow only liquid to pass through. Filter paper acts as a barrier that traps solid particles while allowing liquids to pass through. This helps in separating insoluble impurities from a liquid in processes like water purification and laboratory experiments. For more visiRead more

  5. The correct answer is (B) Wind increases evaporation rate. On a windy day, the moving air carries away water vapor from the surface of clothes, speeding up the evaporation process. This helps clothes dry faster compared to a still, humid environment where moisture remains in the air. For more visitRead more
