Question

why does oil spread over the surface of water?​

Answer 1

Answer:

Oil spreads over the surface of water, whereas, water does not spread over the surface of oil. ... The surface tension of the 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 as such it spreads on the water.

When oil is dropped on the surface of water, the force of surface tension of water being larger than that of oil, stretches the oil drops on all sides. Hence the oil spreads over the surface of water.
