The laws of thermodynamics apply to welldened systems.
Thermodynamics is not concerned about how and at what rate these energy transformations are carried out, but is based on initial and final states of a system undergoing the change. The second law of thermodynamics introduces the notion of entropy s, a measure of system disorder messiness u is the quantity of a systems energy, s is the quality of a systems energy. Maxwell s demon triggered subsequent discussions on the relations between thermodynamics and information processing 15.
