The correct answer is Cohesion.

Surface tension is a property that arises due to the intermolecular forces of attraction among the molecules of the liquid. In the case of mercury taken in a glass tube, adhesive forces are weaker than cohesive forces. So, the mercury molecule does not wet the glass.

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.

Compared to adhesive forces cohesive forces more in mercury.

When liquid water is confined in a tube, its surface (meniscus) has a concave shape because water wets the surface and creeps up the side. Mercury does not wet glass - the cohesive forces within the drops are stronger than the adhesive forces between the drops and glass. Then what's the correct answer?

Cohesion is the correct answer. Because cohesion means cohesion meansCLES OF SAME SUBSTANCE. And Mercury has more cohesive property.

It's cohesion.
