As will be shown in the next section, the energy required for any steady-state flow process is essentially the difference in enthalpy between the products and reactants, plus the amount of energy lost to the surroundings. The change in enthalpy over the process is easily calculated if the enthalpie ...

Microscopic approach - to describe the material in terms of microscopic variables (positions, velocities, charges, etc. of all particles in the system).
