Its is the property of any type of liquid by virtue of which it try to minimize its surface area.
it is measured force acting on imaginary line per unit length that is drown tangential to the free surface of liquid
Mathematically given as
S = F/L = (work done)/(change in area)
It is scalar quantity
Surface tension is the molecular phenomenon cause due to cohesive force.
Surface tension of
liquid depend upon
Surface tension of liquid is independent upon

Surface tension of
- Only Nature of liquid
Surface tension of liquid is independent upon
- The surface area of film
the maximum distance upto which a molecule can exert a force of attraction or repulsion on other molecule is called molecular range
In solid and liquid it is of the order of 10^-9 m .
Surface energy
On increasing the free surface area of liquid ,work has to be done against the force of tension .
this work done stored in liquid surface as a potential energy .
This Additional potential energy per unit area of free surface of liquid is called surface energy.
surface energy = surface tension * increase in surface area .
