Question

Wheat flour can be separated from wheat bran by:

• A. evaporation
• B. sieving
• C. churning
• D. None of these

Answer 1

Answer: (B)

sieving

• Evaporation is used to separate a solid dissolved in a liquid. Both wheat flour and wheat bran are solid.
  
• Sieving is a physical method used for the separation of particles based on their sizes. Wheat flour is separated from bran by using the sieving method because wheat flour particles are finer than wheat bran. Therefore, sieving is used to separate wheat flour and wheat bran.
• Churning is used to separate butter from milk.

So, the correct answer is sieving.
