Water drops cannot stick to the oily surface due to
Lack of adhesive force
Surface tension
Cannot mix each other
Water is lighter than oil
Surface tension
The separation of oil and water is caused due to the difference in surface tension of the two liquids. The water molecules stick together tightly and does not mix with the oil because water molecules are attracted to each other very strongly, forming an invisible โskinโ of surface tension around each drop.
