It is a property by virtue of which the free surface of liquid at rest behaves like stretched membrane tending to contract so as to possess minimum surface area.
Surface tension is the force acting normally on unit length of imaginary line drawn on the surface of liquid. Its unit is N/m.
T = f/ l
Surface tension of a liquid is independent of area of the surface.
A steel needle may be made to float on the surface of liquid due to surface tension.
