Question

what is the surface tension?​

Answer 1

Answer:

Surface tension is the tendency of liquid surfaces to shrink into the minimum surface area possible. Surface tension allows insects, usually denser than water, to float and slide on a water surface.

Answer 2

The tension on the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid, which tends to minimize surface area is generally called as Surface tension. Mathematically, surface tension is the force exhibited by the intermolecular forces divided by the length of the contact line between the phases.
