Surface tension is the force per unit length acting on the surface of a liquid and perpendicular to one side of an imaginary line drawn in the surface.
?Surface tension is the tangential force acting at right angles in the surface of a liquid per
unit length across any line in the surface
? (It is the property that makes a free liquid surface act like a stretched elastic skin).
