Question

___________ (Winnowing/Sieving) is done by using a sieve

Answer 1

Different separation techniques are present depending on the property of the substances to be separated.

sieving method-

• Particles having different sizes can be separated by this technique.
• Since the particles which are large in size remain above the sieve and particles having small size will pass through the sieves (holes) can be collected on another vessel and separated.
• This can be applied if the solid mixtures differ in size.
• Flour is separated from the impurities through this process.

Hence, Sieving is done by using a sieve.
