quantity fuse (kwontitifuz)

See fuse2. contains or is contained by another, and that in three senses: (a) Quantity of extension, or logical breadth, a quantivalence (kwon-tiv'a-lens), n. [ relative character of a term such that when it is in exce the term is predicable of all the subjects of which another is predicable, and of more besides; or a relative character of a concept such that when it is in exce the concept is applicable in all the cases in which another is applicable. (b) Quantity of comprehension or intension, or logical depth, a relative character of a term such that when es the real the predicates thritis in ex more besides; or a relative character of a proposition such that when it is in exce the proposition is followed by all the consequents of another proposition, and more besides. (c) Quantity of science (A quinas) or of information, a relative character of a concept such that when it is in exce it has all the subjects and predicates of another concept, and more besides, owing to its being in a mind which has more knowledge. Logical quantity is to be distinguished from the quantity of a proposition. - Mathematical quantities. See mathematical. - Measurable quantity, a system of quantities every one of which can be stated to any desired degree of approximation by the sums of numerical multiples and submultiples of a finite number of units; a system of quantities embracing only finite quantities together with certain isolated infinities. -Mea sure of a quantity. See measure. Multiple quantity, a quantity which can be exactly expre ed only by means of two or more numbers, as a geographical position. -Natural quantity, quantity in a sense more concrete than the mathematical; quantity as joined to sensible matter, as when we speak of two different but equal quantities of water or lead.-Negative quantity, a fictitious quantity in mathematics, in most cases inconceivable, but never involving any logical contradiction in itself, supposed to belong to a line of quantity continuing the line of ordinary or positive quantity below zero for an infinite distance. In many cases a negative quantity has an interpretation: thus, the negative of a dollar owned is a dollar owed, the negative of a temperature above zero is the same degree of temperature below zero, etc. - Numeral quantity, number. - Parabolic quantity, a quantity belonging to such a system of quantity that on increasing through infinity it immediately reappears on the negative side of zero. Such are Cartes i an coördinates in ordinary geo me try.-Permanent quantity. See permanent. - Physi cal quantity, any character in nature susceptible of more or le , such as velocity, atomic weight, elasticity, heat, electric strength of current, etc. - Positive quantity. See positive. - Predicamental quantity. See predica mental.-Proper quantity. Same as extensive quantity. -Propositional quantity, the quantity of a proposition in logic. See logical quantity, above. - Protensive quantity, duration in time. - Quantity of action, the line integral of the momentum. - Quantity of an eclipse: eclipse. Quantity of curvature, the reciprocal of the radius of curvature. Quantity of electricity, in electrostatics, the amount of electricity upon a charged body. It depends upon the capacity of the body, which, in the case of a sphere, is proportional to the radius (see capacity ), and upon the potential of the electricity. It is numerically equal to the product of these two factors. In electrodynamics it is measured (in coulombs) by the amount of electricity furnished by a current in one second. - Quantity of estate, in law, the time during which the right of enjoyment of the property in question is to continue. - Quantity of heat. See heat, 2. - Quantity of magnetism, the strength of a magnetic pole; the force it exerts upon an equal pole at the unit distance. - Quantity of matter, the ma , as measured by weighing in a balance. - Quantity of motion. See motion. - Quesitive quantity, quantity expre ed by an interrogative numeral. -Radical quantities. See radical. - Rational quan tity, a quantity expre ible by a whole number or fraction See reciprocal . Scalar quant i tivalen ( t )+-ce.] In chem., the combining power or value of an atom as compared with that of the hydrogen atom, which is taken as the unit of measure: same as valence. Also called atomicity.
