Description
Exergy includes external and internal work. Exergy as the external work is defined in the First Law of thermodynamics as a specific form of energy. Exergy as the dissipated Gibbs or Helmholtz energy is the irreversibly dissipated (internal) loss of the potential of performing work as defined in the Second Law of Thermodynamics.
Changes of exergy dG plus bound energy yield the enthalpy change:
dH = dG + T∙dS = dG + dB
