The processes that have Δ S negative has to be determined. Concept Introduction: Δ S is a thermodynamic state function that is known as change in entropy. It depends on initial and final state of a system. In an ideal reversible process, no change in entropy occurs and in an irreversible process, the entropy always increases. If entropy is negative, then reaction is non-feasible and when entropy is positive then reaction is feasible. Entropy is associated to phase change which produces more dispersed particles as is the case with melting or boiling process. Condensing or freezing would be associated with decrease in entropy.

Question

Definition Definition Substance that constitutes everything in the universe. Matter consists of atoms, which are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction: solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
