Vedclass · Answer

(A) For a liquid drop to stick to a solid surface like glass,the force of attraction between the molecules of the liquid and the molecules of the solid surface must be greater than the force of attraction between the molecules of the liquid itself.This force of attraction between different types of molecules is known as the adhesive force.Therefore,the adhesive force must be sufficient to overcome the cohesive force and the gravitational force acting on the drop.
