Input Matter or energy going into a process.
Interconvertibility principle Heat and mechanical work are universally and
uniformly interconvertible in all circumstances. That is, the correlation between
heat and mechanical work in accordance with MEH means causation between
the two: consumption of heat means heat causes work and, vice versa,
consumption of mechanical energy means work causes heat.
Internal reversibility Internal reversibility is not a process operation, but a
condition that a process satisfies: defined as the condition that transient states in
every second-subset of transient states become “at all times infinitesimally near”
their corresponding pairs of equilibrium states of the first subset (See Sect. 6.5).
Kinetic energy Energy of motion, influenced by an objects mass and speed.
Mechanical energy Kinetic energy and potential energy, including pure-exergy
energies that can be converted 100% into kinetic or potential energy.
Mechanical equivalent of heat (MEH) Mechanical energy is produced from the
consumption of heat and, vice versa, heat is produced from the consumption of
mechanical energy. In PETH, the “consumption” of heat is replaced by the
“extraction” of heat.
Mechanical theory of heat (MTH) An ontological theory of heat, on the basis of
which the current “normal science” of thermodynamics has been developed (See
Energy conversion doctrine).
Necessity Necessity is the idea that everything that has ever happened and ever
will happen is necessary, and cannot be otherwise. Necessity is opposed to
chance and contingency, but a distinction can be made between necessity and
determination. This definition is closely aligned with Physical necessity. In that
case, there is no distinction between necessity and determination. Distinction can
be made, however, if one accepts the possibility of causal necessity (see Causal
necessity).
Nomic necessity See Physical necessity.
Non-reversible process Spontaneous natural events are non-reversible processes.
Non-reversible processes are necessarily introduced to differentiate them from
irreversible reversible-like processes since all real processes are irreversible
whether they are non-reversible or reversible-like (See below).
Nuclear energy (atomic) Energy produced by splitting the nuclei of certain
elements.
Output Matter or energy coming out of a process.
PETH Predicative entropic theory of heat (See EGP-centric doctrine).
