The surface tension of water is more than of oil.Therefore when oil is poured over water,the greater value of surface tension of water pulls the oil in all direction and it spreads on the water!

Oil spreads over the surface of water, whereas water does not spread o...
Explanation:
When oil is poured onto the surface of water, it spreads out to form a thin film. This happens because oil has a lower surface tension than water. Surface tension is a property of liquids that arises due to the forces of attraction between the molecules at the surface of the liquid. The surface molecules experience inward forces of attraction due to the presence of neighboring molecules, which causes the surface to contract and form a rounded shape.
Water has a high surface tension due to the strong intermolecular forces between its molecules, which leads to the formation of a rounded shape and a meniscus when it is in a container. Oil, on the other hand, has a lower surface tension due to weaker intermolecular forces between its molecules, which allows it to spread out over the surface of water.
In summary, the reason why oil spreads over the surface of water is due to the lower surface tension of oil compared to water. This property is important in various applications, such as oil spills and emulsions.
