Webirreversibility: 1 n the quality of being irreversible (once done it cannot be changed) Antonyms: reversibility the quality of being reversible in either direction Type of: changelessness , unchangeability , unchangeableness , unchangingness the quality of being unchangeable; having a marked tendency to remain unchanged WebApr 9, 2024 · The problem is here that, by definition, states of equilibrium remain unchanged in the course of time, unless the system is acted upon. Thus, an increase of entropy … In science, a process that is not reversible is called irreversible. This concept arises frequently in thermodynamics. All complex natural processes are irreversible, although a phase transition at the coexistence temperature (e.g. melting of ice cubes in water) is well approximated as reversible.
