Cohesive force between molecules of Mercury is more than adhesive force between molecules of mercury and those of glass. This results in formation of a convex meniscus for surface of mercury. Actually, cohesive and adhesive forces are phenomenon due to surface tension of a liqud. The angle made by mercury from the glass surface is obtuse.
