Physical necessity Necessary sequence of event or relationship in accordance with
laws of physics and chemistry. Physical necessity is a metaphysical
presupposition some philosophers consider that, without which, science
(scientific suppositions) is not possible. Scientific suppositions predicated on
physical necessity are characterized in terms of efficient causation and
determinism.
Poincare range A system undergoes from its initial state to a given final state
spontaneously. Given the initial and final states, there are infinite number of
possible events bookended by the spontaneous event and the reversible event.
The set of all possible events including two bookend events is called Poincare
range.
Potential energy Energy that is stored and that comes from an object’s position or
condition.
Pure exergy energy Energy that 100% of its energy can be converted into
mechanical energy.
Pure spontaneity Systems that their EGPs are not associated with any energy form
change. Typically, isolated systems with spontaneous tendency towards internal
equilibrium possess pure spontaneity.
Quasi-static processes A quasistatic process is an idealization of a spontaneous
natural process. The technical definition is: The set consists of a subset-series of
infinitely dense succession of equilibrium states and the corresponding subsets
of all spontaneous transient states between each pairs of equilibrium states in the
series.
Reversible process Conventional definition: a reversible process is a process
whose direction can be “reversed” by inducing infinitesimal changes to some
property of the system via its surroundings, with no increase in entropy.
Throughout the entire reversible process, the system is in thermodynamic
equilibrium with its surroundings. PETH definition: perfection of reversal-like
processes that are brought about by triadic operation driven by the consumption
of EGP with no entropy growth.
Reversible event A reversible process for a specific Poincare range.
Reversible-like process Reversible-like processes are managed processes driven
by entropy growth potential in triadic operation, which is fundamentally
different from spontaneous processes whereas the former is brought about by
causal necessity the latter is accounted for by physical necessity.
Second law of thermodynamics Entropy growths universally; entropy growth
potential is the universal driver of all changes in nature.
Spontaneity See Entropy growth potential.
