Which property is being used to separate oil and water?
the oil has different particles in it that the water doesn't. therefore the oil floats on top of the water and that the oil is thicker than the water. ^ | | | I believe you're looking for 'physical property'. With more explanation, the viscosity (measure of resistance of liquid) of water is low, that is: less viscous and more fluid (thin), contrast of the viscosity of oil, which is less fluid and more viscous (thick). Oil 'floats' on water because the way the molecules are structured, and what they contain (and don't contain, as stated in the above comment). Water has strong hydrogen bonds that allow its liquid state to be very fluid yet have high tension. Oil has larger clumps of molecules, but do not contain hydrogen. Though a strong bond, the molecule components and structure make the oil more buoyant as it is less dense than water. But there was an experiment that tried to show that oil and water can mix using extreme methods (freezing, thawing, force changes, ect...).
Why does oil float on the water?
Because the specific gravity of oil is lower than that of water. The density of water is 1 g/cm 3 and since the density of oil is less than 1 g/cm 3 it will float. if the density was more than it would sink.
Why is it particularly difficult to separate oil and water once they are mixed?
Water is a polar molecule and has partial positive and negative charges at either end. Oils are usually long hydrocarbon chains, which consist of Hydrogen and Carbon atoms. Hydrocarbons are generally non-polar and have no charge, therefore they cannot attract water. Water is attracted to itself as it has charges and oils are attracted to itself because of intermollecular forces. particles need to be able to intertwine in order to be "mixed", therefore oil and water remain separate.
Dose all plastic float in oil?
plastic will float in water because it is lighter than oil
Does one cup of oil have the same mass as one cup of water?
Oil is less dense than water. Therefore, equal volumes of water and oil will not have the same mass. You can prove this by weighing each. The cup of oil will weigh less.
Water and nonpolar molecules do not easliy mix?
Water and oil doesn't mix because the water is a polar molecule and oil is a non-polar molecule. There will always be more molecules of water than oil.
Why oil does not mix with water?
Water has a polar molecule, while oil has a non-polar molecule. Because of this, oil and water are immiscible.
Why does salad oil not dissolve in water?
Because the oil has a nonpolar molecule and water has a polar molecule.
Why does nt water and oil mix?
Water and oil does not mix because water is molecule and oil is made of hydrocarbon chains. Only molecule substances can mix with molecule solutes.
Why does water and oil separate?
water is a polar molecule. so it doesn't attract to oil (another polar molecule)
Is any oil heavier than water?
Oil heavier than water must have a density greater than 1 gm/cc. In oil field terms, this is stated as an API gravity of 10. There are a number of large deposits of oil with low API gravities. On the related link, descriptions and occurrences of heavy and extra heavy oil are provided.
How does oil spread on water?
well oil is dense than water so it floats and the wind or larger body makes a wave so it pushes it across the water
What is the attraction between a water molecule and olive oil molecule?
They don't attract, in fact they repel, which is why oil and water separate when left for a period of time.
Why does salt water make oil spills get larger?
The solar radiation effects on oil causes it to disperse and spread, leaving a thin layer of oil. Salt water doesn't do much to help since oil and water don't mix without certain chemicals that would damage the environment. Therefore the water has a more dense gravity ratio than oil which salt water's is 1.023 to 1.028 than oil 0.79 to 0.84. therefore the oil is pushed farther up and is the cause of the larger oil spill. Hope this helped.
Name a molecule that does not dissolve well in water?
oil does not dissolve at all in water.
Why doesnt oil and water stick together?
Oil contain non-polar compounds and water has a polar molecule.
What happens when salt is mixed into cooking oil?
Emulsification happens. Emulsification is when it forms an emulsion, which means a colloial suspension of one liquid in another liqiud. Oil floats on top of the water if you let it set becuase water is denser than oil if there are many molecules together. If there is just one molecule of water and one molecule of oil, than the oil would be heavier but since the water molecules are packed closer together, it makes it heavier than oil. Note: If you put washing detergent and oil together and let it set, they will seperate but if you stir it, they will mix together, making a solution.
