What is "vapor"

Vapor \Va"por\, v. i. [imp. & p. p. Vapored; p. pr. & vb. n. Vaporing.] [From Vapor, n.: cf. L. vaporare.] [Written also vapour.]

1. To pass off in fumes, or as a moist, floating substance, whether visible or invisible, to steam; to be exhaled; to evaporate.

2. To emit vapor or fumes. [R.]

   Running waters vapor not so much as standing waters.
   --Bacon.

3. To talk idly; to boast or vaunt; to brag.

   Poets used to vapor much after this manner.
   --Milton.

   We vapor and say, By this time Matthews has beaten them.
   --Walpole.

Vapor \Va"por\, v. t. To send off in vapor, or as if in vapor; as, to vapor away a heated fluid. [Written also vapour.]

He'd laugh to see one throw his heart away, Another, sighing, vapor forth his soul.
--B. Jonson.

Vapor \Va"por\, n. [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.] [Written also vapour.]

1. (Physics) Any substance in the gaseous, or a["e]riform, state, the condition of which is ordinarily that of a liquid or solid.

   Note: 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. [Obs.]
   --Bacon.

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. pl. An old name for hypochondria, or melancholy; the blues. ``A fit of vapors.''
   --Pope.

6. (Pharm.) A medicinal agent designed for administration in the form of inhaled vapor. --Brit. Pharm. Vapor bath.

   1. A bath in vapor; the application of vapor to the body, or part of it, in a close place; also, the place itself.

   2. (Chem.) A small metallic drying oven, usually of copper, for drying and heating filter papers, precipitates, etc.; -- called also air bath. A modified form is provided with a jacket in the outside partition for holding water, or other volatile liquid, by which the temperature may be limited exactly to the required degree.

      Vapor burner, a burner for burning a vaporized hydrocarbon.

      Vapor density (Chem.), 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, esp. a vapor other than steam.

late 14c., from Anglo-French vapour, Old French vapor "moisture, vapor" (13c., Modern French vapeur) and directly from Latin vaporem (nominative vapor) "a warm exhalation, steam, heat," of unknown origin. Vapors "fit of fainting, hysteria, etc." is 1660s, from medieval notion of "exhalations" from the stomach or other organs affecting the brain.

n. 1 cloud diffused matter such as mist, steam or fumes suspended in the air. 2 The gaseous state of a substance that is normally a solid or liquid. vb. 1 (context intransitive English) To become vapor; to be emitted or circulated as vapor. 2 (context transitive English) To turn into vapor. 3 (context intransitive English) To use insubstantial language; to boast or bluster.

1. n. a visible suspension in the air of particles of some substance [syn: vapour]

2. the process of becoming a vapor [syn: vaporization, vaporisation, vapour, evaporation]

In physics a vapor ( American English spelling) or vapour (British) is a substance in the gas phase at a temperature lower than its critical temperature, which means that the vapor can be condensed to a liquid by increasing the pressure on it without reducing the temperature. A vapor is different from an aerosol. An aerosol is a suspension of tiny particles of liquid, solid, or both within a gas.

For example, water has a critical temperature of 374 °C (647 K), which is the highest temperature at which liquid water can exist. In the atmosphere at ordinary temperatures, therefore, gaseous water (known as water vapor) will condense into a liquid if its partial pressure is increased sufficiently.

A vapor may co-exist with a liquid (or a solid). When this is true, the two phases will be in equilibrium, and the gas-partial pressure will be equal to the equilibrium vapor pressure of the liquid (or solid).

A vapor is a substance in the gas phase below its boiling point.

Vapor or vapour may also refer to:

VAPOR (Visualization and Analysis Platform for Ocean, Atmosphere, and Solar Researchers) is a software package developed at the National Center for Atmospheric Research in collaboration with U.C. Davis and Ohio State University. It can produce images and movies from very large mesh-based datasets, such as wind velocity and other physical fields in two and three dimensions. VAPOR has its own input file format, VDF, but it supports conversion from other formats, such as NetCDF, in particular the files output by Weather Research and Forecasting model (WRF).

Vapor ( 1999) is the second novel by American writer Amanda Filipacchi. It was translated into French, Italian, Dutch, Russian, and Polish.

The novel was praised for an energetic originality showcasing a “prodigious postfeminist talent.”
