Splet1. Introduction. Although there is no standard definition of life [1–7], the literature often states that a living system tends to reduce its entropy, defying the second law of thermodynamics to sustain its non-equilibrium (NEQ) existence.However, conforming to the second law of thermodynamics, adjudication between the entropy reduction and … Spletentropy, the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work. Because work is obtained from ordered molecular motion, the amount of entropy is also a measure of the molecular disorder, or randomness, of a system. The concept of entropy provides deep insight into the direction of spontaneous change …

"SpletThe intensive functions of thermodynamics are homogeneous functions of degree zero of the extensive variables. Callen (1960) has shown that the intensive parameters of a thermodynamic system can be written as functions of the extensive variables; that is T = T(S,V,N), P = P(S,V,N), and µ = µ(S,V,N). These expressions are called equations of state " - S variable in thermodynamics
