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 augmentation of an … stranger in a strange land fimfiction

"WebSep 12, 2024 · We first consider ΔS for a system undergoing a reversible process at a constant temperature. In this case, the change in entropy of the system is given by ΔS = Q T, where Q is the heat exchanged by the system kept at a temperature T (in kelvin). If the system absorbs heat—that is, with Q > 0 - the entropy of the system increases. " - Delta e in thermodynamics
