Question

Which of the following method is used to separate bran from flour?

• A. Distillation
• B. Sieving
• C. Handpicking
• D. Evaporation

Answer 1

The correct option is B

Sieving

The explanation for the right answer:

Option B: Sieving

• Sieving is a method of separating the components of a mixture if the components of a mixture differ in size then we have Sieving is a method for separating the components.
• To separate wheat flour from its bran we use this method. Here, small powdered particles of wheat flour pass through the sieve, and the large bran particles remain in the sieve.
• So, the Sieving methods are used to separate the bran from the flour.

The explanations for the wrong answers:

Option A: Distillation

• Distillation is the process of heating a liquid to create vapour, which is collected when cooled separately from the original liquid.
• Hence this method is not used to separate the bran from flour

Option C: Handpicking

• It is a process in which substances in a mixture can be separated by only picking them out with the help of a hand.
• Hence this method is not used to separate the bran from flour

Option D: Evaporation

• The process by which a substance converts into a gaseous state from its liquid state below the temperature at which it boils is called evaporation.
• Hence this method is not used to separate the bran from flour

Conclusion:

• Therefore, the correct answer is option B Sieving.
