Answer :

Mercury molecules have strong forces of attraction between themselves (cohesive forces) and the forces of attraction between molecules of mercury and glass are weak (Adhesive forces).So they form a droplets on the glass surface.


Water molecules have weak forces of attraction between themselves (cohesive forces) and the forces of attraction between the water molecules and glass molecules is strong (adhesive forces). So water spreads on glass.
