ABSTRACT
The article discusses the relation between the heat and chemical energies of the components in deep fluid systems. Topics discussed include the thermodynamic characteristics of individual gases, enthalpy as a thermodynamic function, and the Gibbs free energy. It also mentions that many chemical compounds have negative enthalpies of formation.

    The heat effects of dissolution of water- o-xylene-Triton X-100 microemulsions and their components in 2-propanol at 298.15 K are determined by the thermochemical method. The thermochemical cycle was employed to calculate the formation enthalpies of the microemulsions and to demonstrate that...
