Reversibility can refer to:
*
Time reversibility
A mathematical or physical process is time-reversible if the dynamics of the process remain well-defined when the sequence of time-states is reversed.
A deterministic process is time-reversible if the time-reversed process satisfies the same dyn ...
, a property of some mathematical or physical processes and systems for which time-reversed dynamics are well defined
:*
Reversible diffusion, an example of a reversible stochastic process
*
Reversible process (thermodynamics)
In thermodynamics, a reversible process is a process, involving a system and its surroundings, whose direction can be reversed by infinitesimal changes in some properties of the surroundings, such as pressure or temperature.
Throughout an enti ...
, a process or cycle such that the net change at each stage in the combined entropy of the system and its surroundings is zero
*
Reversible reaction
A reversible reaction is a reaction in which the conversion of reactants to products and the conversion of products to reactants occur simultaneously.
: \mathit aA + \mathit bB \mathit cC + \mathit dD
A and B can react to form C and D or, in the ...
, a chemical reaction for which the position of the chemical equilibrium is very sensitive to the imposed physical conditions; so the reaction can be made to run either forwards or in reverse by changing those conditions
*
Reversible computing, logical reversibility of a computation; a computational step for which a well-defined inverse exists
*
Reversible error, a legal mistake invalidating a trial
*
Reversible garment, a garment that can be worn two ways
*
Piaget's theory of cognitive development, in which mental reversibility is part of the concrete operational stage, the understanding that numbers and objects can change and then return to their original state
*
Reversible playing card, a playing card that may be read either way up
