Is mixing oil and water a physical or a chemical change?
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.
