yes cohesion is responsible
This is because of cohesive property
It's cohesion
. Cohesion
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.
Please correct the answer this is due to cohesion property of fluid not surface tention
