Irreversible process examples
WebMost quasi-static processes are irreversible. The issue comes down to the following: the term quasi-static applies to the description of a single system undergoing a process, whereas the term irreversible applies to the description of the process as a whole, which often involves multiple interacting systems.. In order to use the term quasi-static, one has … WebIn irreversible processes, mass transfer occurs through a finite chemical potential difference. • An example of an irreversible process is a spontaneous chemical reaction, or electrochemical reaction. • Δ Stotal > 0 means that no single process is possible for which the total entropy decreases. • For cyclic processes: View chapter Purchase book

WebIrreversible processes are characterized by the flow of fluids with friction, and sliding friction between any two matters. • An example of an irreversible process is electric current flow … WebA reversible mixture is the addition of sugar to water. Sugar crystals dissolve, or break apart, when stirred into water. If this mixture is heated, the water evaporates, leaving the sugar crystals behind. An irreversible mixture is cement powder and water. This combination results in a hard solid, and it cannot be reversed.
