Vedclass · Answer

(A) The shape of a liquid drop is determined by the competition between cohesive forces $(C.F.)$ and adhesive forces $(A.F.)$.When a water drop is placed in oil, it forms a sphere because the cohesive forces between water molecules are stronger than the adhesive forces between water and oil molecules $(C.F._{water} > A.F._{water-oil})$.Conversely, when an oil drop is placed in water, it spreads because the adhesive forces between oil and water molecules are stronger than the cohesive forces between oil molecules $(A.F._{water-oil} > C.F._{oil})$.Therefore, the primary reason for the water drop remaining spherical in oil is that the cohesive force of water is greater than the adhesive force between water and oil.

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