The two ways you can separate nails from sand is by digging it up and raking it :)
The weight of the nails would not change after being on the sand for two days unless the sand gets stuck to the nails. Sand typically does not significantly add weight to objects unless it accumulates in large amounts.
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.
One way to separate a mixture of sand and sugar is by using a sieve or filter. The smaller particles of sugar will pass through, while the larger particles of sand will be left behind. Another way is to dissolve the mixture in water, as sugar will dissolve while sand will not. The sugar solution can then be filtered to separate the sand.
You should use a magnet to separate iron from sand. Iron is magnetic, so it will be attracted to the magnet and easily separated from the sand. A strainer would not work in this case as it would not be able to separate the two based on their magnetic properties.
Put the sand in a dish and heat it above the melting point of lead. The lead will flow to the bottom and separate from the sand. Due to the high density of the lead, the sand will float on the molten lead. When the lead and sand cool, you can separate the two.
No, it's a physical change because you can still separate the two from each other.
Two ways are evaporation and distillation.
Distillation for the two soluble liquids (which seperates them by their boiling point) and magnetism for the separation of iron pins and sand.
For the nails, you can use a magnet. You can separate the marbles and corks by putting it in water, wood floats and marbles don't.
Try a magnet!
One way the beach gets its sand is from ruins of rock and wearing away of shells and particles on the beach.
Yes, you can use evaporation to separate sand and water. By heating the mixture, the water will evaporate leaving behind the sand. This method is effective for separating the two components without the need for specialized equipment.
