Because oil is less denser than water water is very denser so it goes down, oil is less denser so it goes up there's more information but I just know about this one sorry I don't know the other answers
{Answer Improved}
I am in chemistry right now this semester and this question popped up in one of our "In-Class Discussion Questions." ((even though we had to do these questions for homework)) But anyway, yes. The reason oil floats on water is because it is less dense than the water. Reason being, is the forces which are being contrasted between these two substances. One force, I am pretty sure all of us have heard of, is the Gravitational Force, and the other is called Buoyancy Force. The gravitational force is the force which pulls an object closer and closer to the ground, (or in this case, the two substances of course) and buoyancy force is the force which causes objects (or the oil in this case) to float on water. Where the oil is less dense than the water, the upward force on the oil is greater than that of the downward force of gravity on the oil. The dissimilarity of these forces is what causes the oil to rise above the water. So yes, it is because of the oil being less dense, but the cause of it being less dense is because of the forces of gravity and buoyancy.
Not only that, but on top of these forces there is also a statement used in chemistry about substances: like dissolves like, which means that a substance tends to dissolve in another substance if the molecules of the two substances have similar electric dipoles. If you don't understand what an electric dipole is, I think of it as a battery basically a magnet. An electric dipole has a positive (+) charged end and a negative (-) charged end. The magnitude of the (+) end can sometimes be greater than that of the (-) end, and the (-) end cans sometimes be greater than that of the (+) end. The difference of the magnitudes between the two charges and the distance depends on the strength of the dipole. Therefore dipoles with similar strengths dissolve more precipitously than dipoles with different strengths.
I'm sure there is more to it then just this information
What else can I help you with?
What Oil floats on water because it is denser true or false?
Oil floats on water because water is denser than oil.
Oil floats on water because its density is what on water?
Type your answer here... the oil has more density
What scientific concept explains why oil floats on water?
Oil floats on water due to differences in their densities. Oil has a lower density than water, so it floats on the surface. This is because molecules in oil are less tightly packed compared to water, allowing them to remain on top.
Why does vetcable oil float on water?
Vegetable oil floats on water because it is less dense than water. Density is the mass of a substance divided by its volume. Since the mass of vegetable oil is less than the same volume of water, it displaces less water and floats on top.
If oil floats on water which liquid has a higher specific gravity?
If oil floats on water, it means that oil has a lower specific gravity than water. Specific gravity is the ratio of the density of a substance to the density of a reference substance (usually water for liquids). Since oil is less dense than water, it will float, indicating that the specific gravity of oil is less than 1, while water has a specific gravity of approximately 1.
What Oil floats on water because it is denser true or false?
Oil floats on water because water is denser than oil.
Does oil or water have a lower density?
Oil floats on water, and has a lower density.
Which oil sink in water?
No. Oil floats on water because it is less dense than water.
Why does water go straight to bottom when mixed with oil?
Water is heavier than oil. Oil floats on water.
Is the density of water more then the density of oil?
Cooking oil has a density of 910 to 930 kilograms per cubic meter or 0.91 to 0.93 grams per cubic centimeter. Therefore it is lighter than water and floats on it.
Oil floats on water because its density is what on water?

Does oil create a barrier on top of water?
oil is less dense then water so oil floats on top of water.
How does an oil slick form when an oil tanker springs a leak?
Oil and water do not mix. Oil floats to the surface of the water.
Does oil have a density or water?
Oil and water each have densities. Oil is less dense than water, so it floats above it.
Do cornoil float on water?
Corn oil floats on water. It floats because oil is less dense than water. When one substance is less dense than another it rises to the top.
What liquid floats on water?
gasoline/petrol,,,,,,,,,,, oil base products
