The reversible work of formation of unit area of new surface by cleavage. It has previously been called specific
surface work
, surface energy, surface tension or surface
free energy
. The symbol recommended is γπ in preference to σ because of the confusion with
surface charge density
. The superficial work γπ is a scalar quantity and consequently is
isotropic
