What would happen if you mix oil sand and water in a cup?

Sand is at the bottom; water above and above water the oil.


When you mix sand and water it sinks to the bottom so what do you call that?

It is called a residue solution. Meaning that sand is heavier than water, after the process of mixing each other it settles down to the bottom of the water.


What happen when you mix sand and water?

it will not affect each other because the sand is solid while water is liquid. that form is now called heterogeneous mixture.


Why is sand considered sediment?

Sand is sediment because it settles to the bottom of the water and gunks together. Sand is s very small grain.


How would you separate sand from water into their components?

sand is opaqe,water is transparent First add the sand to water. Then filter the sand from water by a filter paper. This process is called filtration. Filtration is the process by which an insoluble solid is separated from a liquid. Sand will remain as residue on the filter paper and the water will be in in the beaker. Sand will be wet, so leave the sand outside so that the water will evaporate. Sedimentation - The process by which heavy particles settle down and get separated from the liquid is known as sedimentation. The sand settles at the bottom and the water will be on top, although this method will only allow the layers to get separated. So you won't get the sand and water in separate beakers. Decantation- Pouring out the clear liquid leaving behind the sediment is known as decantation. First add the sand to water. The mud will settle at the bottom of the beaker. The water will be on top, so now pour out the liquid to another beaker. You must be careful while doing this step, because if you disturb the solution the sand will get mixed with water. Then again you have to wait till the sand settles down at the bottom of the beaker.

What will be the outcome of mixing sand with with water?

The sand will simply go to the bottom of the container of water. Water and sand do not mix.


Why does sand sink to the bottom of water?

Sand has a higher density than water, so it sinks to the bottom when placed in water due to gravity pulling it down. The sand particles are heavier and more compact than water molecules, causing them to settle at the bottom.


What would happen if you stirred water and sand?

If you stirred water and sand together, you would have a mixture of water and sand until the sand sinks to the bottom.


Can you reverse sand and water?

no. The water is the solvent and the sand is the insoluble material. When you have a insoluble material it sits at the bottom. Sand is more dense then water.


What would happen if you mix oil sand and water in a cup?

Sand is at the bottom; water above and above water the oil.


What happen when sand mixed with water?

Nothing - sand and water do not react because sand is relatively inert. The sand will sink to the bottom of the container because it is significantly heavier than the water.


Does water go through the sand at the bottom of the ocean?

No! Because the currents under the water, down that deep, does not arrouse the sand and the water is not then moved

What happens to sand when it gets wet?

Some of the sand will sink to the bottom of the water. There is no chemical reaction. However, some of the sand may go into suspension, making the water muddy. This is a physical change that can be reversed by filtering the muddy water.


When you add sand to water why does the sand settle at the bottom of the water?

Sand is heavier then water (denser) so it sinks. If you add oil to water, oil is less dense (lighter) than water so it floats.


What will happen if we put saltsand and water?

The salt will dissolve in the water, and make the water salty. The sand won't be dissolved, and the sand will sink to the bottom of the container.


How could you separate a mixture of sand and water?

Let it sit. Sand is more dense than water, and will sink to the bottom of the solution.
