30 words match “MOLECULAR”

MOLECULAR a.
Pertaining to, connected with, produced by, or consisting of, molecules; as, molecular forces; molecular groups of atoms, etc. Molecular attraction (Phys.), attraction acting between the molecules of bodies, and at insensible distances. -- Molecular weight (Chem.), the weight of a molecule of any gas or vapor as compa…
MOLECULARITY n.
The state of consisting of molecules; the state or quality of being molecular.
MOLECULARLY adv.
With molecules; in the manner of molecules. W. R. Grove.
BIMOLECULAR a.
Pertaining to, or formed from, two molecules; as, a bimolecular reaction (a reaction between two molecules).
INTRAMOLECULAR a.
Between molecules; situated, or acting, between the molecules of bodies.
ABSORB v.
To take up by cohesive, chemical, or any molecular action, as when charcoal absorbs gases. So heat, light, and electricity are absorbed or taken up in the substances into which they pass. Nichol. p. 8
ABSORPTION n.
An imbibing or reception by molecular or chemical action; as, the absorption of light, heat, electricity, etc.
ADHESION n.
The molecular attraction exerted between bodies in contact. See Cohesion.
COERCIVE a.
of a bar to its natural state when active magnetism has ceased. It plainly depends on the molecular constitution of the metal. Nichol. The power of resisting magnetization or demagnization is sometimes called coercive force. S. Thompson.
CONDENSATION n.
of one or more substances into a distinct and definite compound of greater complexity and molecular weight, often resulting in an increase of density, as the condensation of oxygen into ozone, or of acetone into mesitylene. Condensation product (Chem.), a substance obtained by the polymerization of one substance, or by…
DISSIPATIVE a.
riction and resistances of other kinds are introduced without regard to the heat or other molecular actions which they generate; -- opposed to conservative system.
DOUBLE a.
es or basic radicals, as the double carbonate of sodium and potassium, NaKCO3.6H2O. (b) A molecular combination of two distinct salts, as common alum, which consists of the sulphate of aluminium, and the sulphate of potassium or ammonium. -- Double shuffle, a low, noisy dance. -- Double standard (Polit. Econ.), a dou…
ELECTRICITY n.
conducting substance or space. It is generally brought into action by any disturbance of molecular equilibrium, whether from a chemical, physical, or mechanical, cause.
ETCHING n.
ppropriate solvent. They have usually a definite form, and are important as revealing the molecular structure. -- Etching needle, a sharp-pointed steel instrument with which lines are drawn in the ground or varnish in etching. -- Etching stitch (Needlework), a stitch used outline embroidery.
HEAT n.
the sense of feeling. In its nature heat is a mode if motion, being in general a form of molecular disturbance or vibration. It was formerly supposed to be a subtile, imponderable fluid, to which was given the name caloric.
ISOMERIC a.
e., having the same elements united in the same proportion by weight, but with different molecular weights; as, acetylene and benzine are isomeric (polymeric) with each other in this sense. See Polymeric. (b) Metameric; i. e., having the same elements united in the same proportions by weight, and with the same molecul…
ISOMERISM n.
nces, which, while chemically identical (in that they have the same composition, the same molecular weights, and the same ultimate constitution), are yet physically different, as in their action on polarized light, as dextro- and lævo-tartaric acids. In such compounds there is usually at least one unsymmetrical carbon…
METAMERIC a.
Having the same elements united in the same proportion by weight, and with the same molecular weight, but possessing a different structure and different properties; as, methyl ether and ethyl alcohol are metameric compounds. See Isomeric.
NECROBIOSIS n.
The death of a part by molecular disintegration and without loss of continuity, as in the processes of degeneration and atrophy. Virchow.
NECROSIS n.
of bone, or the death of a bone or portion of a bone in mass, as opposed to its death by molecular disintegration. See Caries.
