Surface tension of a liquid is independent of the area of the surface.

Explanation

Surface tension of liquid is the force exerted by the molecules lying on one side of an imaginary line of unit length on the molecule lying on the other side of the line which is perpendicular to the line and parallel to the surface is defined as the surface tension of the liquid.
`therefore` Surface tension `S=(F)/(l)`
The surface tension is independent of the area of the liquid surface.
