In physics, an entropic force acting in a system is an emergent phenomenon resulting from the entire system's statistical tendency to increase its entropy, rather than from a particular underlying force on the atomic scale.[1][2] The entropic force can be considered as an emergent of the entropic interaction. The concept of entropic interaction was usually used in a subjunctive mood. For example: "macromolecule links, as if, entropically repulse from each other at a short distance and entropically are attracted to each other at a long distance”.[3] In a modern view[4][5] the entropic interaction is considered to be a real-life interaction, and it is viewed as a mutual influence of open thermodynamic systems on each other by means of transferring information about their states, changing their entropies and translation of these systems into more probable conditions.
