Question

In sieving, components of a mixture are separated due to the difference in their

• A. texture
• B. colours
• C. sizes
• D. weights

Answer 1

The correct option is C sizes

Sieving is a technique which uses a mesh to separate things on the basis of differences in their size.
The bigger the holes of a sieve the greater the size of the particles that can pass through it. If the holes in a sieve are very small then only very fine particles can pass through it.
For example, in a fishing net the holes in the net are big enough that except for fish anything else simply passess out from the net. When you make tea, the sieve used to separate the tea leaves has very tiny holes so that only the liquid tea can pass through it.
