| vapor density | The mass per unit volume of a vapor; since the vapor density changes with temperature and pressure, it is commonly expressed as a specific gravity, i.e., the weight of the vapor divided by the weight of an equal volume of a reference gas (e.g., oxygen or hydrogen) at the same temperature and pressure.

| vapor | To send off in vapor, or as if in vapor; as, to vapor away a heated fluid. Alternative forms: vapour] "He'd laugh to see one throw his heart away, Another, sighing, vapor forth his soul." (B. Jonson) 1. <physics> Any substance in the gaseous, or aeriform, state, the condition of which is ordinarily that of a liquid or solid. The term vapor is sometimes used in a more extended sense, as identical with gas; and the difference between the two is not so much one of kind as of degree, the latter being applied to all permanently elastic fluids except atmospheric air, the former to those elastic fluids which lose that condition at ordinary temperatures. The atmosphere contains more or less vapor of water, a portion of which, on a reduction of temperature, becomes condensed into liquid water in the form of rain or dew. The vapor of water produced by boiling, especially in its economic relations, is called steam. "Vapor is any substance in the gaseous condition at the maximum of density consistent with that condition. This is the strict and proper meaning of the word vapor." (Nichol) 2. In a loose and popular sense, any visible diffused substance floating in the atmosphere and impairing its transparency, as smoke, fog, etc. "The vapour which that fro the earth glood [glided]" (Chaucer) "Fire and hail; snow and vapors; stormy wind fulfilling his word." (Ps. Cxlviii. 8) 3. Wind; flatulence. 4. Something unsubstantial, fleeting, or transitory; unreal fancy; vain imagination; idle talk; boasting. "For what is your life? It is even a vapor, that appeareth for a little time, and then vanisheth away." (James iv. 14) 5. An old name for hypochondria, or melancholy; the blues. "A fit of vapors." 6. <pharmacology> A medicinal agent designed for administration in the form of inhaled vapor. Vapor bath. A bath in vapor; the application of vapor to the body, or part of it, in a close place; also, the place itself. <chemistry> The relative weight of gases and vapors as compared with some specific standard, usually hydrogen, but sometimes air. The vapor density of gases and vaporizable substances as compared with hydrogen, when multiplied by two, or when compared with air and multiplied by 28.8, gives the molecular weight. Vapor engine, an engine worked by the expansive force of a vapor, especially. A vapor other than steam. Origin: OE. Vapour, OF. Vapour, vapor, vapeur, F. Vapeur, L. Vapor; probably for cvapor, and akin to Gr. Smoke, to breathe forth, Lith. Kvepti to breathe, smell, Russ. Kopote fine soot. Cf. Vapid Alternative forms: vapour.

| vapor pressure | The partial pressure exerted by the vapor phase of a liquid. (05 Mar 2000) |
| mercury vapor lamp | A lamp in which the electric arc is in an ionised mercury vapor atmosphere; it produces ultraviolet light that can be used therapeutically or in diagnostic photometry. (05 Mar 2000) |
| bone density | Bone density is the amount of bone tissue in a certain volume of bone. It can be measured using a special X-ray called a quantitative computed tomogram. (12 Dec 1998) |
| bulk density | Weight per unit of volume, usually specified in pounds per cubic foot. (05 Dec 1998) |
| buoyant density | The density that allows a substance to float in some standard fluid. (05 Mar 2000) |
| very low density lipoprotein | <biochemistry> A lipoprotein substances (combination of a fat and a protein) which acts as a carrier for cholesterol and fats (particularly triglycerides) in the bloodstream. Elevations in very low density lipoprotein in the bloodstream are associated with an increased risk of atherosclerosis and coronary artery disease. Acronym: VLDL (18 Nov 1997) |
| centrifugation, density gradient | Separation of particles according to density by employing a gradient of varying densities. at equilibrium each particle settles in the gradient at a point equal to its density. (12 Dec 1998) |
| photon density | The number of counted events recorded in scintigraphy per square centimeter or per square inch of imaged area. Synonym: count density. (05 Mar 2000) |
| count density | The number of counted events recorded in scintigraphy per square centimeter or per square inch of imaged area. Synonym: count density. (05 Mar 2000) |
| population density | <epidemiology> Number of individuals in a population relative to space. (12 Dec 1998) |
| current density | <radiobiology> Amount of current flowing through a substance, per unit area perpendicular to the direction of current flow. (See also density) (09 Oct 1997) |
| high density lipoprotein | <biochemistry> These lipoproteins acts to carry cholesterol in the bloodstream. Raised high density lipoprotein levels have been correlated with a lower risk for heart disease. Less than 35 mg/dl is considered a positive risk factor for coronary artery disease, over 60 mg/dl is considered a negative risk factor (reduces your risk of heart disease). Recent studies show a low high density lipoprotein level is the strongest predictor of cardiovascular death in women. Acronym: HDL (18 Nov 1997) |
| spin density | The number of nuclear dipoles per unit volume. (05 Mar 2000) |
| vapor density | the density of a gas relative to the density of hydrogen |
