Every earth-bound system is an atomic-molecular system. Collections of smaller interactive atomic or molecular systems, over time, react to form larger molecular systems. Molecular systems evolve or behave according to the following atomic-molecular evolution principle:

In short, the valence electrons of any molecular system will tend to evolve in such a manner so as to achieve the configuration of maximum stability. Thermodynamically, the Gibbs free energy is simply a measure of the chemical work involved in each of these processes. Another way of stating this evolution process, according to the combined law of thermodynamics, for constant temperature, constant pressure, systems, such as earth, is that each system will tend to configure or evolve in such a manner so as to minimize its Gibbs free energy.
