Reversibilitási

Reversibilitási is a concept used in Hungarian academic discourse to describe the property of a system, process, or operation that can be reversed to return to its original state. In practice, reversibilitási denotes reversibility across several fields, each with its own precise meaning.

In thermodynamics, a reversible process is an idealized path in which the system changes state in a way that, if slightly perturbed, the process can be reversed with no net entropy production and no lasting effects on the surroundings.

In chemistry, reversible reactions are those that proceed in both directions; at equilibrium, the forward and reverse rates are equal, and a mixture contains both reactants and products in balance.

In mathematics and computer science, a reversible transformation is invertible: there exists a unique inverse function or operation that recovers the original input. Reversible computing studies logic circuits that preserve information to reduce energy dissipation.

Practical limits apply: many real processes are only approximately reversible, due to irreversibilities such as friction, viscosity, heat transfer, or information loss. The concept provides a theoretical benchmark for efficiency and for understanding the fundamental constraints on real systems. Reversibilitási thus serves as a cross-disciplinary framework for examining how and when processes can be undone or reversed, and what that implies for energy, state, and information.
