A hydrocolloid (heterogenous) mixture
This is a heterogeneous mixture.
The oil will rise to the top and float on the water.
Each layer is a phase.
Oil is not as dense as water. So, even when they are mixed, the water molecules can still slide down in between the oil molecules, thereby causing the oil molecules to form a layer on the surface of the water.
immiscible - oil and water miscible - water and ethyl alcohol
No. The oil should drain off of the water. Water and oil don't mix, so there would be no contamination. If there is something else mixed with the oil, though, it can possibly mix with the water.
Water is heavier than oil. Oil floats on water.
Alcohol mixed with water is generically called grog.
The oil will rise to the top and float on the water.

Not a lot, water and oil don't mix and so the oil will float on top of the water.
oil
Water mixed with oil? Oil mixed with water? White smoke out of tailpipe? Lack of compression on 2 adjacient cylinders?
Oils and water are not miscible.
Because of different densities; being density of oil lower than water density, this makes oil float on water
The oil and water will separate into two layers with oil as the top layer.
Oil and water do not mix, however, when they are stirred or mixed thoroughly the particles of oil will become too small to see.
