Preferred Label : superficial work;
Detailed label : superficial work in surface chemistry;
IUPAC definition : 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 γ π in preference to σ because of the confusion
with surface charge density. The superficial work γ π is a scalar quantity and consequently
is isotropic.;
