Select a suitable word from those given and write it in the space provided:

sieving, winnowing, loading, evaporation, decantation, filtration, condensation, distillation, sedimentation, sublimation

A mixture of stones is allowed to fall through wire nets in order to separate them according to different sizes. This is a process of ____________.

Answer 1

• Sieving is a separation technique based on the difference in particle size.
• Sieving is used when components of a mixture have different sizes. Sieving is a simple method of separating particles of varying sizes.
• Sieve plates have meshed bottoms that allow only particles of a specific size to pass through them. The size of mesh can vary from one place to another depending upon its application.

Hence, a mixture of stones is allowed to fall through wire nets to separate them according to different sizes. This is a process of sieving.
