Most (but not all) oil is less dense than water. That oil which is less dense than water will float. That oil which is denser than water will sink.
more dense substances sink, less dense substances float. oil will not sink in water, it will float, it is less dense.
Oil does not sink in water. Almost all oils and fats are less dense than water so they will float.
No, it is not. Oil and water do not mix. If you pour oil into water, the oil will float to the surface. If you pour water into oil, the water will sink to the bottom and the oil will float on top.
because of the salt in the water
I have a marker which float in water.
it won't cuz
A plastic always sink in oil like a plastic bottle will always float in oil.
does Arsenic float or sink
does water sink or float in what? whether one solution "floats" or "sinks" when added to a 2nd solution depends largely on the relative densities of the two solutions. Generally the denser of the two will "sink", though other factors, such as polarity, come into play in certain situations (eg, mixing oil and alcohol).
it will float as long as it is not fully covered water.
This depends on the type of oil. Few types of oil sink in water, while most types of oil float on top of the water.
