The property which forms the basis of sieving
Answers
Answer:
Explanation:
Most of the things that we come across in our day-to-day life exist as a mixture of two or more pure substances. We need to separate these pure substances from the mixture in order to use them individually. For example, you must have noticed that we don’t use the flour bought from the vendors directly for cooking chapatti. We use certain separation techniques in order to separate the flour from the impurities attached to it. We generally use sieve plates for the separation of flour from the bran particles or other impurities. These sieve plates allow the fine flour particles to pass through the holes of the sieve plate while the bigger impurities are unable to pass through it and remain on the sieve. This method of separation of particles from a mixture based on the difference in size of particles is known as sieving. It uses sieve plates for separation of coarse particles from finer particles.
Answer:
The property which forms the basis of sieving is differences in size.
Explanation:
- Sieving is used to separate materials when the particle size is too fine to pick up by hand.
- It uses a filter with holes of a specific size.
- The sieve traps the larger particles while allowing the smaller ones to flow through.
- This technique, for instance, is used to separate flour from bran, sand from gravel, different-sized pearls, etc.
- Sieving is the process of removing particles from a mixture based on differences in particle size.
- For separating coarse from fine particles, sieve plates are used. Plates used in sieves have bottoms that are mesh- or perforated-like, allowing only particles of a certain size to pass through.
