Preferred Label : surface pressure;
IUPAC definition : The change of interfacial tension caused by addition of a given species to a base
solution. When an area of liquid covered with a spread substance is separated from
a clean area of surface by a mechanical barrier, the force acting on unit length of
the barrier is called the surface pressure, π or π s, and is equal to γ 0- γ where
γ 0 is the surface tension of the clean surface and γ that of the covered surface.;
