Thermal energy applied to particles in conservative vector fields results in an increase in the
potential and kinetic energy causing an increase in entropy. However, conservative fields
associated with potential energy gradients of the system act in opposition to the kinetic
energy gradients reducing the overall accessible states of the system and its entropy. Thus,
entropy can be expressed as the ratio of difference between the input energy and potential
energy of the system to its temperature. As the input energy represents the changes in
Hamiltonian of the system, entropy can also be expressed as the difference in changes
of its Hamiltonian and potential energy. Formulation of entropy in terms of the changes
in system Hamiltonian and potential energy changes give novel insights on the role of
potential fields in determining entropy rate and its impact on order and equilibrium.
