Vedclass · Answer

(B) When a liquid does not wet the surface,the cohesive forces between the liquid molecules are stronger than the adhesive forces between the liquid and the solid surface.This results in the liquid forming a convex meniscus.For a convex meniscus,the angle of contact $	heta$ is always greater than $90^{\circ}$.Therefore,the angle of contact is obtuse.

If a liquid does not wet the surface,its angle of contact is acute or obtuse?
