Vocabulary : Pharynx to Phase splitting

Pharynx : The part of the alimentary canal between the cavity of the mouth and the esophagus. It has one or two external openings through the nose in the higher vertebrates, and lateral branchial openings in fishes and some amphibias.
Phascolome : A marsupial of the genus Phascolomys; a wombat.
Phase : A homogenous, physically distinct portion of matter in a system not homogeneous; as, the three phases, ice, water, and aqueous vapor. A phase may be either a single chemical substance or a mixture, as of gases. ;; In certain birds and mammals, one of two or more color variations characteristic of the species, but independent of the ordinary seasonal and sexual differences, and often also of age. Some of the herons which appear in white and colored phases, and certain squirrels which are sometimes uniformly blackish instead of the usual coloration, furnish examples. Color phases occur also in other animals, notably in butterflies. ;; The relation at any instant of a periodically varying electric magnitude, as electro-motive force, a current, etc., to its initial value as expressed in factorial parts of the complete cycle. It is usually expressed in angular measure, the cycle beb four right angles, or 360. Such periodic variations are generally well represented by sine curves; and phase relations are shown by
Phase angle : The angle expressing phase relation.
Phase converter : A machine for converting an alternating current into an alternating current of a different number of phases and the same frequency.

Phase displacement : A charge of phase whereby an alternating current attains its maximum later or earlier. An inductance would cause a lag, a capacity would cause an advance, in phase.
Phase meter : Alt. of Phasemeter
Phase rule : A generalization with regard to systems of chemical equilibrium, discovered by Prof. J. Willard Gibbs. It may be stated thus: The degree of variableness (number of degrees of freedom) of a system is equal to the number of components minus the number of phases, plus two. Thus, if the components be salt and water, and the phases salt, ice, saturated solution, and vapor, the system is invariant, that is, there is only one set of conditions under which these four phases can exist in equilibrium. If only three phases be considered, the system is univariant, that is, the fixing of one condition, as temperature, determines the others.
Phase splitter : A device by which a single-phase current is split into two or more currents differing in phase. It is used in starting single-phase induction motors.
Phase splitting : The dephasing of the two parts of a single alternating current in two dissimilar branches of a given circuit.
