It depends on what kind of oil you are using
|
Detailed explanation-1: -In fact, oils are hydrophobic, or “water fearing.” Instead of being attracted to water molecules, oil molecules are repelled by them. As a result, when you add oil to a cup of water the two don’t mix with each other.
Detailed explanation-2: -So what happens when you try to mix oil and water? The water molecules attract each other, and the oil molecules stick together. That causes oil and water to form two separate layers. Water molecules pack closer together, so they sink to the bottom, leaving oil sitting on top of the water.
Detailed explanation-3: -Question: When you mix salad oil and water, they immediately separate because: Salad oil is hydrophobic O Hydrogen bonds reform between water and salad oil It depends on what kind of oil you are using Salad oil is too heavy.
Detailed explanation-4: -Oil does not dissolve in water so it is insoluble in water but floats on the surface of water.
