The gaseous phase of liquids or solids at atmospheric temperature and pressure.

‚ A substance in the gas state that is below its critical temperature but still suspended in air. It is possible for a vapor to be liquefied by increased pressure. Vapors are usually not visible. [Env [..]

Gaseous form of substances. Vapors diffuse and can be changed to a solid or liquid state by an increase in pressure or decrease in temperature.

The gas given off by substances that are solids or liquids at ordinary atmospheric pressure and temperatures.

Water vapor, essentially. It is what gives electronic cigarettes the name "vapor cigarettes," and is the smoke-like substance that comes out of the e-cigarette carrying the nicotine.

 -  the mist produced by vaporizing e-liquid in an electronic cigarette.

The gaseous state of a substance.

A substance in the gaseous state, capable of being liquefied by compression or cooling.

Vapor in equilibrium with its liquid; i.e., when the numbers per unit time of molecules passing in two directions through the surface dividing the two phases are equal.

Vapor at a temperature which is higher than the saturation temperature (i.e., boiling point) at the existing pressure.
