How could you separate a mixture of sand and gravel?
by filtering it. :)
Firstly, sift the mixture to separate the gravel from the sand and salt. Now place the sifted mixture into water. The sand will sink to the bottom and the salt will eventually dissolve. Pour this watery mixture through filter paper to catch all of the sand. If you want the salt back in solid form, simply boil the water.
If you have a mixture of gravel and sand and salt and iron fillings what properties of these substances could you use to separate the mixture and how would you use those properties?
Sift to separate everything from the gravel. Then use a magnet (If needed) to pull out the iron. Now you are left with sand and salt. Dump this mixture into water. The sand should sink to the bottom. The salt should dissolve. Pour the mixture through filter paper to catch the sand. Boil the water and it will evaporate. Now you are left with salt.
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…
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.
If we need to separate sand and gravel, we simply use the size of the material and a mechanical contraption to do the separating. A screen with mesh of the proper or appropriate dimensions will sieve the particles nicely. The sand will fall through the mesh piling up underneath it, and, if the screen is tilted, the gravel will bounce its way down and off the screen into a separate pile.
