I believe the best answer for this question is "entropy." Entropy is a scientific term referring to thermodynamics. It measures both the order and the disorder of a system. Order, or disorder, are both defined by how close the system is to equilibrium. Hope this helps. Also, keep in mind to ask questions in the proper category - this would be most suited to science, rather than English. Thanks.
