## superficial work

in surface chemistry
https://doi.org/10.1351/goldbook.S06142
The reversible work of formation of unit area of new surface by cleavage. It has previously been called specific @S06193@, surface energy, surface tension or surface @F02515@. The symbol recommended is $$\gamma _{\pi }$$ in preference to $$\sigma$$ because of the confusion with @S06159@. The superficial work $$\gamma _{\pi }$$ is a scalar quantity and consequently is @I03353@.
