- n. An exhalation of moisture; any visible diffused substance, as fog, mist, steam, or smoke, floating in the atmosphere and impairing its transparency.
- n. In physics, the gaseous form which a solid or liquid substance assumes when sufficiently heated. Vapor is essentially gas, and, since all known gases have now been proved to be liquefiable, no physical difference can be said really to exist between an ordinary gas, such as oxygen, and a vapor, such as steam. In common language, however, a difference is usually recognized: a gas is a substance which at ordinary temperatures and pressures exists in the gaseous state, while a vapor is the gaseous form of a substance which normally exists in a solid or liquid form. An important distinction exists between a saturated vapor (one which is on the point of condensation) and a non-saturated vapor (one which can be compressed or cooled to a certain extent without condensation). The latter obeys Boyle's and Gay-Lussac's laws of gases; in the former, however, increased compression produces condensation, but does not change the pressure of the vapor, which is a function of the temperature alone. Superheated steam is a non-saturated vapor. Aqueous vapor is always present as a minor constituent of the atmosphere, and its amount, which is very variable both at different places on the earth's surface and in the same locality at different times, forms an important element of climate. By a reduction of temperature the aqueous vapor in the air is brought to the socalled state of saturation, and then condensed into cloud, mist, and rain. See
