These sites explain it much better than I ever could. I hope this helps.
the chemicals don't react
I think that it deals with the denisties of thsoe substance.s Oil has less density than water and therefore they does not mix.
Oil and water have different densities.
because the density of water is 1 while the density of oil is less than water tat is 0.8 and water can get mix with anything whose density is greater than it's density value.
Chemically water is a Polar molecule. That means it has poles like a magnet. It dissolves materials and mixes with other materials that have this trait. Oil is a non-polar molecule. This means that it has no poles and is not attracted to water.
oil is heavier than water. densities are too different...opposites don't attract
the density differences in the two materials make the oil float on top of the water, but it is their chemical attractors that keep them separate. Water's bond to other water molecules is so strong that it resists the oil molecules attraction to the water molecules. The tight bonds resist the mixing and the two substances stay separated.
In special cases water and oil can actually bond, but this involves human interaction.
density(oil) < density(water)
so oil floats over water
oil is more dense than water is, which causes it to sink to the bottom
Water is too thin and Oil is to thick!!
it's natural
because of its difference in mass.
oil and water dont mix because their densities are different.
because the compounds in valved inthe maters
their densities varies , the adhesive nature in oil is more when compared to water, their visos nature also varies.
