When a system reaches its steady state, the entropy production becomes stabilized at a corresponding minimum ('Principle of'PRIGOGINE ) and the level of entropy becomes constant. This is possible only because the system is able to transfer to its environment the entropy that it permanently produces.
If some disturbance takes place, due to a small increase or decrease of some gradient, the flow will automatically be modified in such a way as to nullify the effects of the disturbance and maintain the steady state.
This condition, proper to the systems in a steady state', may be compared with the Principle of'LE CHATELIER in physical and chemical systems.
