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.

Cohesion is correct answer.

I think Cohesion, surface tension is produced by cohesion. Cohesion is attractive force within the same type molecules, of this opposite is adhesion.

Cohesion is the correct answer.

Cohesion is absolutely right answer. Forces between mercury is greater than adhesion forces.

Cohesion is the correct answer.

The reason is cohesion. Due to cohesive force between the molecules of mercury droplet it shows high surface tension and which is also the cause of capillary fall in capillary tube. Higher the cohesiveness lesser the tendency to wet the surface.

It's cohesion.

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

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?
