  • Interesting fact: Even when all the molecules in a single breath of air have been dispersed evenly in the earth's atmosphere, there will still be one or two of the same ones taken into the lungs with every subsequent breath. Every time you breathe in, you inhale one or two of the same molecules that you inhaled with the first breath you took as a baby.

    • n atmosphere The aëriform fluid which surrounds the earth, and extends to an undetermined height above its surface; the air. It is a mechanical mixture of 79 parts by volume of nitrogen and 21 of oxygen, with a trace of carbon dioxid and a variable quantity of aqueous vapor, ammonia, ozone, and organic matter. The composition of the normal atmosphere varies but slightly in different localities, although near towns it usually contains impurities, such as sulphuric acid, hydrochloric acid, etc. The movements of the atmosphere constitute the winds, and in it are formed or produced clouds, rain, and snow. Its density is greatest at the earth's surface, and decreases as the height above the earth increases. The atmosphere, like other bodies, gravitates toward the earth, and therefore has weight and exerts pressure. Its average weight at the level of the sea is about 15 pounds (14.7) to the square inch.
    • n atmosphere A conventional unit of atmospheric pressure. An atmosphere is in English use the pressure of a vertical column of 30 inches of mercury at the freezing-point at London; in French use it is the pressure of 760 millimeters of mercury at the freezing-point at Paris. For the absolute atmosphere in the C. G. S. (centimeter-gram-second) system, see absolute. The weight of the atmosphere to the square inch is commonly employed as a convenient unit for pressures arising from other causes, such as the weight of liquids, the force of steam, etc.: thus, a pressure in a steam-boiler of 3 atmospheres means a pressure equal to 45 pounds per square inch.
    • n atmosphere The gaseous envelop surrounding any of the heavenly bodies.
    • n atmosphere Any gaseous medium: as, “an atmosphere of cold oxygen,” Miller.
    • n atmosphere An assumed outer envelop of force, effluvia, etc., surrounding a body: as, an electrical atmosphere.
