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.

∙ 14y agoMost oils are much larger molecules and are heavier than one molecule of water, but due to the way that water molecule interact, most importantly the hydrogen bonding interactions, the molecules pack much closer together and form a more dense liquid. Oils are primarily composed of carbon and hydrogen which do not hydrogen bond like water does. This results in a much less dense liquid which will float on water.

Wiki User
∙ 12y agoMainly yes, though there are some oils that are heavier.
Wiki User
∙ 11y agolighter...that's why oil mixed with water floats on the top
Wiki User
∙ 12y agoNo. Water is heavier than oil.

Does an egg float in water with flour?
In a mixture of oil and water, the two will separate with the oil on top. If the water has enough solute in it (salt, sugar), the egg will float in the water, but not above the oil. An egg is denser than fresh water, but less dense than salt water. It is denser than most oils.
Is water denser or oil?
Denser means a comparison between two things and if something is heavier than the other Denser means a comparison between two things and if something is heavier than the other
Does oil pour faster than water?
No, oil does not pour faster than water
Which is denser oil or water?
what i think is oil is denser because denser mean mass which is heavy and that is why the oil goes on the bottom when you add oil with water
What happens if oil and water are mixed together without an emulsifier?
Water is denser than oil because particles in the oil are more separated between each other than in water. This results in oil rising to the top, while water stays at the bottom of the recipient.
Is water lighter than vegetable oil?
No water is heavier then oil.
Is petrolium oil heavier than water?
Oil 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.
Other than density why can oil and water not mix?
oil and water never mix together. water is heavier than oil. so,oil float on the water.
Why do items fall through water easier than oil?
Becaus oil is thicker and heavier than water
Does a cup of water have more grams than a cup of oil?
Yes, because water is heavier than oil.
What is heavier heating oil or water?
Water is heavier.
Is oil heavier than water?
The short answer is, it depends on which oil you're talking about. There are many different things that are considered "oils". For the most part, an oil is: hydrophobic (is repelled by water / doesn't mix with water), a liquid at 25°C, and is soluble in (mixes with) organic solvents. How 'heavy' something is is determined by density. One way to describe the density of a liquid is by giving its 'specific gravity', which means how heavy is it compared to water. The specific gravity of water is 1, so any oil with a specific gravity greater than 1 will sink in water, while any oil with a specific gravity lower than 1 will float on water. Most things that people are likely to encounter that they call 'oil', such as motor or vegetable oil, are lighter than water, but there certainly are oils that are heavier than water.
In the case of the gulf oil spill would not the oil be heavier?
Crude Oil is less dense than water.
How does the oils density compares to water?
Oil like coconut oil,petrolium flot on water.So they have low density than water
Why duse oil and water not mix?
Because water is heavier than oil.So oil is lighter and it floats above the water surface.That is why when there are oil spills, you can esily see oil float over water.
Are some fluids heavier than other fluids?
Yes. Try mixing oil and water.
