Generally, water is more dense than hydrocarbons. The density of water is about 1 gram per cubic centimeter, while the density of hydrocarbons like oil and gasoline is typically less than 1 gram per cubic centimeter. This is why oil floats on water.
The question is against my experience -- oil floats on water and hence oil density is lower than water density.
Oils are generally hydrophobic -- dislike bonding with water. On the other hand, water molecules like to stick together, because of hydrogen bonds.
Oil molecules tend to spread out more because of the carbon-bonding molecular structure -- it is harder to fit two twisting organic molecules into a tight space than water molecules, which are much smaller.

Is chlorine less dense or more dense than water?
Chlorine gas is less dense than water, so it will float on top of water if the two are in contact.
Does lithium sink under water?
No, lithium is less dense than water, so it will float on the surface of water.
Is oil less dense then water?
Kerosene and turpentine are less dense than engine oil. So is water and rubbing alcohol and other common liquids.
Is ice more or less dense than than liquid water?
Ice is less dense than water at the same pressure. That is why ice cubes and icebergs float on the water.
Is ice as dense as water?
Ice is less dense than water, that's why it floats.
Is water less or more dense than water?
Ice is less dense than water
Why petroleum float on water?
Petroleum floats on water because it is less dense than water. This is due to the composition of petroleum, which includes a variety of hydrocarbons that have lower density than water. When spilled in water, petroleum will stay at the surface due to its lighter density.
Why will water not extinguish a hydrocarbon fire?
Most hydrocarbons are less dense than water. So, if you put water on a hydrocarbon fire, they will simply float on top of it, rending the water ineffective.
What object is less dense than water?
A wooden block can be less dense than water.
Is ice less dense or more dense than water?
no
Can you make oil less dense than water?
Oil IS already less dense than water.
What fruit is less dense than water?
Easy, put a fruit in water and if it floats it is less dense than water.
Is chlorine less dense or more dense than water?
Chlorine gas is less dense than water, so it will float on top of water if the two are in contact.
Does ice float because it is less dense than water?
Yes. Anything that is less dense than water will float on water.
What is less dense water basalt iron or granite?
Water is less dense than any of the other materials listed.In order of density from least to highest:Water (least dense)GraniteBasaltIron (most dense)
Is a rubber ducky more dense then water?
No, a rubber duck is less dense than water. It will float on the surface of the water because it is less dense.
Is Jupiter less dense than water?
No, the only planet in the solar system less dense than water is Saturn.
