Surface tension is borne out of the cohesion forces existing between the similar molecules of the liquid. It is nothing but the consequence of cohesion forces. Hence the answer is correct.

The correct answer is cohesion that means the same kind of particle are attract to each other that leads to they are adjust in a minimum possible area. That also called as surface tension.

Surface tension is one of them in which force of attraction bw molecules increases.

Shahaji said:   1 decade ago
The correct answer is surface tension. And both forces are related with it, so cohesion is more correct than adhesive force.

Kaushal said:   1 decade ago
It is objectionable to call it surface tension because cohesion & adhesion are types of surface tension.
So to be more specific, cohesion is the right answer.

It would be better to say that it is due to surface tension.

Cohesive force takes place only in high density fluids like mercury. Only surface tension could cause this effect.

Thanks Amani.

Amani said:   1 decade ago
Cohesion means force of attraction between same molecules of a liquid. So, the free surface of a liquid behaves like a sheet and tends to contract to the smallest area.

Surface Tension is also one of the answer.

More correct answer to the question is Surface Tension.
