Oil like coconut oil,petrolium flot on water.So they have low density than water
Oil is heavier than water so it sinks to the bottom.
That is the specific gravity of the substance.
That is the specific gravity of the substance.
The oils have low density as compared to water and oils are non polar organic compounds while water is a polar compound, so oil can not mix with water and floats on waters surface.
density is mass divided by volume
density
That is the specific gravity of the substance.
hydrometer
That is the specific gravity of the substance.
You need to specify the oil, since there are many oils having different densities. Some oils are less dense than water, while some oils are more dense than water. Motor oil has a density of about 0.876 g/mL ; while water has a density of about 1.000 g/mL.
its because of the oils density
it has oils in it
"Specific gravity" or "specific density"
Different oils have different densities; usually a bit less than the density of water.
Oil is heavier than water so it sinks to the bottom.
The term is correctly specific gravity (also relative density) which compares the density (typically in g/cm3) to that of water (which is practically 1 g/cm3).
The oils have low density as compared to water and oils are non polar organic compounds while water is a polar compound, so oil can not mix with water and floats on waters surface.
