Question

Explain why oil spreads over the surface of water while water does not do so..

Answer 1

Answer:

Hello mate..

Explanation:

Oils spread over surface of water whereas water do not spreads over the surface of it why. The surface tension of the water is more than that of oil. Therefore,when oil is poured over water,the greater value of surface tension of water pulls oil in all directions,and as such it spreads on the water

Answer 2

Answer:

1). The surface tension of oil is less than the surface tension of water.

2). thus, when oil is dropped on the surface of water ,it spreads in all directions due to the higher force of surface tension of water
