First law thermodynamics

Thermodynamic, first law Energy can be converted from one form to another but it cannot be created or destroyed. 

This is an odd formula at first sight since temperatures generally do not add up, but it turns out to be easy to embrace when it is understood that the PIT is not a temperature but a numerical indicator of the dual affinity of the surfactant for its physicochemical environment, i.e., an energy term that is usually summed up as in the thermodynamics first law.
