Irreversible process example

WebApr 8, 2024 · In simpler terms, the meaning of irreversible is a process that can be reversed without leaving any trace on the surroundings. Irreversible in the process can be owed to the interaction of that system with other processes. An ideal example of this process would be the singular swing of a frictionless pendulum. WebExamples of irreversible processes include the following: (a) a chemical reaction in which a precipitate forms; (b) the explosive combination of hydrogen and oxygen to form water; (c) the diffusion of perfume vapor into air. Irreversible processes occur spontaneously within a system that is not in thermodynamic equilibrium.

WebJun 28, 2024 · A reversible process is one where d S u n i v = 0, while d S u n i v > 0 indicates a (spontaneous) irreversible process. In a reversible process, the entropy change of the system and surroundings are equal and opposite. In an irreversible process, we generate extra entropy. We can assign that "extra" irreversible entropy either to the system or ... WebAn irreversible process is a process that cannot return both the system and the surroundings to their original conditions. That is, the system and the surroundings would not return to their original conditions if the process was reversed.

WebReversible processes occur when a system returns to its original state after being disturbed. A classic example of this is the water cycle. A classic example is melting ice and vice … WebMelting or freezing of ice in water is an example of a realistic process that is nearly reversible. Additionally, the system must be in (quasistatic) equilibrium with the surroundings at all time, and there must be no dissipative effects, such as friction, for a process to be considered reversible.
