2 Ans: For seperating slightly larger sized impurities. 
3. Ans: Winnowing is used to separate heavier and lighter components of a mixture by wind or by blowing air.
4.Ans : Evaporation 
5. Ans: Winnowing 
6.Ans : Handpicking
7.Ans: We separate fine flour and powdered chalk by saving because sieving allows the fine flour to pass through the holes of the sieve while chalk will remain on sieve.
8.Ans: Churning is the process of shaving up cream or whole milk to make butter.

Q1. Among different components of mixture there are many substances which are harmful or not useful for us.to remove these harmful or unuseful components we need to separate them.
Ans. We need to separate harmful and undesirable substances from the mixture.
Q2. Handpicking can be used to separate the then consecutions of mixture only when the consecution of the mixture is easily visible and can be separated.
Ans. Handpicking can be used to remove many harmful substances only when they are visible clearly.
Q3. PRINCIPAL-The technique is performed using wind or air. The light particles get blown up by air and thus get separated from the heavy substances. The principal that is used in the process is winnowing.
Ans. The principle behind this technique is that it is perfomed by the wind by the light particles get away and the heavy particles gets collected.
Q4. The easiest way to separate a mixture of sugar and water is used to distillation, a process that separates substances based on their different boiling point.
Ans. The method that is used to separate sugar crystals and salt is sieving.
Q5. Winnowing
Ans.  The process of separating heavier and lighter components of a mixture by wind or by blowing air is called winnowing.
Q6. husk can be separated from black gram and sand by winnowing sand and black germ can be separated sieving.
Ans. No, husk can be separated by the sieving and sand andblack germs can be separated by winnowing. 
Q7. sieve the flour to separate any impurities in it.now, make a fine powder of chalk pieces and mix it with the flour. Sieving is used when components of a mixture have different sizes. 
Ans. .No , we cannot separate flour and powdered chalk by sieving because the particles of chalk and flour are not different in size so chalk powder will not be retained in the sieve .]]> 2020-07-29 08:05:23 UTC https://padlet.com/manmeetkr2008/xu286fav89g39y8i/wish/664843404 angelssingh5 https://padlet.com/manmeetkr2008/xu286fav89g39y8i/wish/664844609 Daksh Lamba 6D part 1]]> 2020-07-29 08:08:33 UTC https://padlet.com/manmeetkr2008/xu286fav89g39y8i/wish/664844609 angelssingh5 https://padlet.com/manmeetkr2008/xu286fav89g39y8i/wish/664844746 Daksh Lamba 6D part 2
