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 verb
Usage 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."
