Vedclass · Answer

(D) liquid does not wet a solid surface if the angle of contact is obtuse, i.e.,greater than $90^{\circ}$.In this condition, the cohesive forces between the liquid molecules are stronger than the adhesive forces between the liquid and the solid surface.Consequently, the liquid tends to minimize contact with the surface, resulting in the liquid not wetting the solid.
