Explain the time seiving state the structure of a sieve and explain the separation of given size particle by sieving?

$\huge{\boxed{\mathfrak{Answer:-}}}$

Sieving - is a method of separation, which is used for separating substances of different sizes that cannot be separated in hand picking.

- is a method of separation, which is used for separating substances of different sizes that cannot be separated in hand picking. Principle - Based on the difference in size of the solid particles.

Technique of Separation - The large sized particles are separated from the small or finer particles by passing the mixture through a sieve.

• The sieve has a wooden frame, with a metal mesh at its base. The mixture is added from the top of the sieve, when the larger particles stay above and the finer particles collect below it on shaking the sieve.

Examples - Separation of rice powder from soil, separation of different sized particles of diamond and of sand.
