Sand itself doesnt take the shape of the container its all of sand put together that takes theshape of a container. if you just get a single grain of sand...its not going to take the shape. you need a lot of it.
solids
only sand
Sand is made of small pieces of solid rock.
Because it is made up of small, solid particles.
Sand and sugar are two examples of solids that can be poured easily. When poured, their small particles flow and settle into molds or containers, taking the shape of the surface they are poured onto.
Insoluble solids are substances that do not dissolve in a particular solvent, typically water. They remain as solid particles suspended in the solvent. Examples include sand, chalk, and sulfur.
Solids that do not dissolve are called insoluble solids. These substances do not dissolve in water or other solvents due to their chemical properties. Examples include sand, chalk, and plastic.
The water will just be re cycled without being cleaned, the sand removes minute particles of solids.
No, not at all. In fact most solids are INsoluble. Some solids (such as metals, stones, wood) don't dissolve while other solids like sugar or salt do dissolve. Water is a polar molecule, therefore it can dissolve only polar substances and many ionic compounds. However, it cannot dissolve non-polar substances.
That depends on the temperature. At normal Earth surface temperatures, sand is a solid. Heat it up and it becomes a liquid, heat if further and it will vaporize.
Err, well Solids are called Solids because there solid (unbreakable) unless you burn (melt) the solid but this can only work with some solids eg plastic, also sometimes you can snap solids eg Chocolate bar. But most Solids are not separatable. You could also use things like magnets which sort of attach things that are metal- only works if things are metal. ((SCF)) Solids can dissolve in solutions. For examples sugar dissolve in water. Now lets take a mixture of two solids for example sand and sugar. If you mix sand with water it doesn't dissolve. However the sugar will. If you put your sand/sugar mixture in water, the sand will still be in the solid form but the sugar will be in solution (dissolved in water). To get the sand you just need to filter the solution (a bit like when you cook pasta and get rid of the water by sieving it). You will get the solid sand in on your filter paper. You also can get the sugar back. After filtering, only sugar will be remianing in solution. By evaporating the water, solid crystals of sugar will appear. Et voila! That's how you can separate two solids. When two solids dissolve in the same solvents, that becomes more complicated. As the person who answered before me said, sometimes you can use magnets....
No. Sand consists of tiny grains of rock. The bits of rock vary somewhat in composition, but generally do not contain molecular solids. Sand is mostly composed of covalent networks and ionic solids.
