Also, esp. Brit., vapour. [1325–75; < Latin vapor steam] va′por•a•ble, adj. va`por•a•bil′i•ty, n. va′por•er, n. va′por•less, adj. va′por•y, adj. va·por (vā′pər)1. The gaseous state of a substance that is liquid at room temperature. Because the carbon dioxide gas associated with dry ice is often referred to as a vapor, some scientists classify the gaseous state of substances that are solids at room temperature as vapors as well.2. A faintly visible suspension of fine particles of matter in the air, as mist, fumes, or smoke.3. A mixture of fine droplets of a substance and air, as the fuel mixture of an internal-combustion engine.
vaporize verbUsage When we use the words vapor and steam, we usually think of a fine mist or other visible suspension of particles in the air. We speak of the steam that clouds the bathroom after we take a shower or the vapor in the jet of water droplets that appears a short distance from the end of a boiling tea kettle. But to a scientist, this kind of talk is inaccurate. The word vapor refers to a gaseous state of a substance, and not to a mist of liquid droplets or fine solid particles. For instance, the fumes that arise when volatile substances such as alcohol and gasoline evaporate are (not surprisingly) a vapor. Similarly, the visible stream of water droplets that rush out of the spout of tea kettle is not steam. As the gaseous state of water heated past its boiling point, steam is invisible. Usually, there is a clear space of an inch or two between the spout and the beginning of the visible stream of droplets. This space contains steam. The steam loses its heat to the surrounding air, then falls below the boiling point and condenses in the air as water droplets. It is not, scientifically speaking, water vapor.vapor- atmosphere - Derives from Greek atmos, "vapor," and sphaira, "globe," and is literally "ball of vapor."
- brume, brumous - Brume is a poetic term meaning "mist, fog, or vapor"; brumous means "foggy."
- damp - The noun first meant "vapor, steam," or "smoke"—especially that which was harmful or noxious.
- transpire - Had an early sense of "emit as vapor through the surface"—from trans-, "through," and spirare, "breathe."

TranslationsIdiomsSeeget the vaporsVapor
vapour (US), vapor1. particles of moisture or other substance suspended in air and visible as clouds, smoke, etc. 2. a gaseous substance at a temperature below its critical temperature 3. a substance that is in a gaseous state at a temperature below its boiling point Vapor the gaseous state of matter that arises when the gas phase of a substance is in equilibrium with the liquid or solid phase of the same material. As a rule, the term “vapor” is used when a phase equilibrium is achieved at temperatures and pressures that are characteristic of natural occurring conditions. For example, one speaks of the vapors of alcohol, benzene, iodine, and naphthalene. However, the term “vapor” is also used to refer to the gaseous state of water above the critical values of temperature and pressure, even though such values are not obtained under spontaneous, natural conditions. Conversely, CO2 is referred to as a gas below the critical temperature of 31.04°C, even though by strict usage gaseous CO2 is a vapor, since it is found in the gaseous state under spontaneous, natural conditions (seeCRITICAL STATE). The terms “gas” and “vapor” are interchangeable in the terminology of the thermodynamics of phase transformations. The vapor of a chemically pure substance is saturated at the saturation temperature and pressure and unsaturated at temperatures above the saturation temperature when the value of pressure is fixed. Unsaturated vapor, which in industrial terminology is called superheated steam or, simply, gas, is less dense than saturated vapor. A vapor is supersaturated when the pressure is raised above the saturation pressure while the temperature is kept constant. A. N. GUREEV vapor[′vā·pər] (thermodynamics) A gas at a temperature below the critical temperature, so that it can be liquefied by compression, without lowering the temperature. vapor
