Irreversible
Reversible changes are processes that allow a substance to return to its original state. Examples include the melting of ice into water, which can freeze back into ice; the boiling of water into steam, which can condense back to liquid; and dissolving sugar in water, which can be reversed by evaporation. Other examples include the stretching of rubber, the folding of paper, the magnetization of certain metals, the expansion of gases when heated, the mixing of sand and salt, and the transformation of wax when heated and cooled.
Soluble in water, sand is not.
I would use the property of solubility in water; sugar is highly soluble in water and sand is highly insoluble.
Firstly, water is to be added to make sugar water solution. The the total mixture of sand and sugar-water solution is passed through filter paper. The sand separates out and sugar water solution is collected in a vessel. Then by evaporating sugar is collected.

Sandy water, which typically refers to a mixture of sand and water, is generally considered irreversible. Once sand is mixed with water, it can settle and form a suspension or a slurry, but separating the sand from the water completely may require filtration or sedimentation, and may not restore the original state of the sand and water. While some physical processes can separate them, the mixing alters their original conditions, making it largely irreversible under normal circumstances.
Yes, sand and water can be separated through a physical process called filtration, making it a reversible change. By passing the mixture through a filter, the sand particles are retained while the water passes through, effectively separating the two components.
Because - you can simply evaporate the water by heating it, and collect the water in a separate vessel - leaving the dry sand intact.
Yes, the mixing of sand and gravel is a physical change, which means it is generally reversible. You can separate sand and gravel by using methods like sieving or washing, as their different sizes and densities allow for such separation. However, the ease of separation may depend on the specific mixture and the method used.
That depends on what is being mixed together. Two examples of this are: If you mix sand, gravel, and water it is reversible and you can separate the mixture back to its original three parts. If you mix sand, gravel, water, and cement powder it is not reversible as the water will react with the cement powder creating liquid cement and the sand and gravel will form concrete with the liquid cement. After a few hours the liquid cement in the concrete will set and the concrete mixture will become as hard as rock. It is now no longer possible to separate the mixture back to its original four parts.
Sieving sand from stones is a physical process that separates the two based on their size differences. This process is reversible because the sand and stones can be easily separated again by using the same sieving method. By passing the mixture through a sieve, the smaller particles (sand) will fall through the sieve while the larger particles (stones) will be left behind, allowing for the separation to be reversed.
to separate the mixture of sand and sugar:- first: you can mix water in it and after mixing you can separate the water and sand. and after that you boil the water until whole water is evaporated and you get sugar and sand separated. second: if difference b/w size of sugar and sand particle you can use met to separate them.
l,
yes, just evaporate water and you are left with sand
When sugar and sand are mixed together, they can be physically separated because they are not chemically bonded. However, the properties of the original substances remain unchanged even after mixing since it is a physical combination and not a chemical reaction.
Yes, the process of turning sand into glass is irreversible. Once the sand has been melted and transformed into glass through heating and cooling, it cannot be reverted back to its original sand form.
