Physical ... it's only a state change. Cool it and it reverts to its old condition.
It is a physical change because the oil and the water do not change in chemical composition.
Oil floating on water is not a "change", so asking whether it's a physical change or a chemical one is nonsense. To the extent there's any meaning at all to the question, it's a phenomenon caused by the physical properties of the two materials.
Oil and water do not mix because they have different polarities. When oil and water are mixed, they separate into distinct layers due to their different densities. This separation is a physical change where the molecules of each substance retain their original properties.
chemical change. the dressing and mayonnaise changed completely to form the sauce.
physical change hunnythe color would be the property of the oilbut as you can see the color changesthe chemicals do not

It is a chemical change.
physical- there's no chemical change.
Yes, the fractionation of crude oil is a physical change because it involves the separation of its components based on their physical properties such as boiling point, without changing the chemical composition of the substances.

Pumping oil is considered a physical change because it involves a change in state or location of the oil without altering its chemical composition. The oil remains the same substance before and after pumping, only its position or state has changed.
When oil and water mix it is due to an emulsifier being added to the solution. The emulsifier has one hydrophobic tail which will attach to the oil and one hydrophilic tail which attaches to the water. It is more of a chemical change than a physical one since the oil and water don't change state, however they will not form an emulsification without an aid so its technically not due to a chemical reaction between the water and oil alone either.
Initially it'll be a chemical change...but a rusted oil drum is also a weakened one, and (especially if you piled other drums on top of it) it could change shape through applied external forces lower than ones normally needed to change the shape of an oil drum, and that would be a physical change.
