Mercury does not wet the glass because the cohesive force with the drops is stronger than the adhesive force between the drops and glass.

?Tamanna ?? 3 years, 10 months ago

Mercury does not wet glass - the cohesive forces within the drops are stronger than the adhesive forces between the drops and glass. When liquid mercury is confined in a tube, its surface (meniscus) has a convex shape because the cohesive forces in liquid mercury tend to draw it into a drop.
