is sieving sand from stones reversible?
Yes
To separate salt, sand, and stones, you can use a combination of methods such as sieving, dissolving, and settling. First, sieve out the stones to separate them from the sand and salt. Then, dissolve the salt in water and filter it to separate the saltwater from the sand. Finally, evaporate the water to recover the salt, leaving behind the sand.

One way to separate sand from baking soda is by using the method of sieving, where a sieve is used to filter out the larger sand particles from the smaller baking soda particles. Another method is to use water to dissolve the baking soda, leaving the heavier sand particles behind. Finally, you can also try using a magnet to attract any iron filings mixed in with the sand and baking soda.
The science term for sifting is "sieving." Sieving involves passing a mixture through a sieve or mesh to separate particles based on their size.
It is not a reversible change. During boiling some components are extracted with hot water from the crushed dried leaves. It is impossible to restore the original leaves.
Examples: sieving of sand, sieving of flour, dimensional sorting of peas and beans, etc.
A simple method is sieving.
Irreversible

Then, dissolve the salt in water and filter it to separate the saltwater from the sand. Finally, evaporate the water to recover the salt, leaving behind the sand.

Use a sieve to remove the paper clips and small stones. Heat the remaining solution until the water evaporates (which is recovered by condensation). This will leave the salt behind.

u can put your hand and grad the paper clip.
yes, just evaporate water and you are left with sand
no it is irreversible change
you pick out the stones, secondly you have to use filtering to pick out the sand and just leave the sugar.
