In science:

Rather, if the reservoirs are allowed to come into thermal and mechanical contact, a mean value results which optimizes the work output and heat uptake, and is entirely reversible.
The thermodynamics governing 'endoreversible' engines
In this section we establish that the final mean temperature and volume, determined from adiabatic equilibration, yields maximum work output and maximum heat uptake with respect to all other admissible sets of temperatures and volumes.
The thermodynamics governing 'endoreversible' engines
The principle of maximum heat uptake in an isothermal process can be established in a similar manner.
The thermodynamics governing 'endoreversible' engines
This establishes the maximum property of the heat uptake in an isothermal process when the final state has the volume given by (14).
The thermodynamics governing 'endoreversible' engines
Maximum work output and heat uptake arise when the reservoirs, initially at different temperatures or volumes, are allowed to interact, thermally or mechanically, and whose final mean values are determined by adiabatic equilibration.
