Subject field(s)
  • Analytical Chemistry
  • Fluid Mechanics and Hydraulics (Physics)
DEF

A substance in the gaseous state that is capable of being liquified by compression or cooling.

DEF

The gaseous form of a substance that is found in a solid or liquid state at normal atmospheric pressure.

OBS

Often confused with vapor, steam should not be used as a synonym for "vapor" unless the said vapor is generated from water.

French

  • Chimie analytique
  • Mécanique des fluides et hydraulique (Physique)

Record 2 2003-11-14

English

Subject field(s)
  • Atmospheric, Climatic and Meteorological Phenomena
  • Hydrology and Hydrography
  • Climatology
DEF

Any substance existing in the gaseous state at a temperature lower than that of its critical point; that is, a gas cool enough to be liquefied if sufficient pressure were applied to it.

OBS

Since the critical temperature for water (374°C) is far above any atmospheric temperatures (except for the extreme upper air), all water substance found in the atmosphere in the gaseous state is appropriately called water vapor.

OBS

"Vapor" is the North American spelling and "vapour" the British spelling.

OBS

Carbon dioxide and sulphur dioxide are also technically vapours at atmospheric temperatures, but in their low concentrations are not liquefied in the ranges of pressure and temperature that exist in the atmosphere.

French

Domaine(s)
  • Phénomènes météorologiques, climatiques et atmosphériques
  • Hydrologie et hydrographie
  • Climatologie
DEF

État d'un fluide occupant tout l'espace qui lui est offert, au-dessous de sa température critique Tc. Au-dessus de Tc, la vapeur devient un gaz.

OBS

En météorologie, le terme «vapeur» est généralement employé au sens de «vapeur d'eau».

Spanish

Campo(s) temático(s)
  • Fenómenos meteorológicos, climáticos y atmosféricos
  • Hidrología e hidrografía
  • Climatología
DEF

Gas cuya temperatura es inferior a la crítica.
