(a) What is Sieving?
(b) What is Sublimation?
Answers
Answer:
Sieving:
The process of separating fine particles from the larger particles by using a sieve, is called sieving. ... We're fine flour particles that are separated from bigger impurities by using a seam. So the process is called the process of separating fine particles from the larger particles by using a sieve.
sublimation:
Sublimation is the conversion of a substance from the solid to the gaseous state without its becoming liquid. It occurs more frequently among substances that are close to their freezing point.
Answer:
Sieving is a simple technique for separating particles of different sizes. A sieve such as used for sifting flour has very small holes. Coarse particles are separated or broken up by grinding against one another and the screen openings. ... Sieves are also used to separate stones from sand.
Explanation:
Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state. ... The reverse process of sublimation is deposition or desublimation, in which a substance passes directly from a gas to a solid phase.
