A water drop takes the shape of a sphere in a oil while the oil drop spreads in water, because
(A.F.=adhesive force C.F.=Cohesive force )

Oil drop may……. On a hot water.

When a drop of water is dropped on oil surface, then

Explain why some oils spread on water, when others float as drops.

Oil spreads on cold water but remains as drop on hot water.

"On cold water oil spreads, but on hot water it remains in the form of drops." Why?

A mercury drop continues to be spherical inside the water which proves that as compared to the adhesive force between water and mercury molecules , the cohesive forces between mercury molecules are
