Answer:

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