Air vs. Ether — What's the Difference?

The invisible gaseous substance surrounding the earth, a mixture mainly of oxygen and nitrogen.

Ethers are a class of organic compounds that contain an ether group—an oxygen atom connected to two alkyl or aryl groups. They have the general formula R–O–R′, where R and R′ represent the alkyl or aryl groups.

An impression of a quality or manner given by someone or something

Any of a class of organic compounds in which two hydrocarbon groups are linked by an oxygen atom.

A tune or short melodious song

A volatile, highly flammable liquid, C4H10O, derived from distilling ethyl alcohol with sulfuric acid, used as a reagent and solvent, and formerly used as an anesthetic. Also called diethyl ether, ethyl ether.

A jump off the ground on a snowboard or skateboard.

The regions of space beyond the earth's atmosphere; the heavens.

Express (an opinion or grievance) publicly

The element believed in ancient and medieval civilizations to fill all space above the sphere of the moon and to compose the stars and planets.

Expose (a room) to the open air in order to ventilate it

(Physics) An all-pervading, infinitely elastic, massless medium formerly postulated as the medium of propagation of electromagnetic waves.

A colorless, odorless, tasteless, gaseous mixture, mainly nitrogen (approximately 78 percent) and oxygen (approximately 21 percent) with lesser amounts of argon, carbon dioxide, hydrogen, neon, helium, and other gases.

The substance formerly supposed to fill the upper regions of the atmosphere above the clouds, in particular as a medium breathed by deities.

This mixture with varying amounts of moisture and particulate matter, enveloping the earth; the atmosphere.

(by extension) The medium breathed by human beings; the air.

The sky; the firmament.

(by extension) The sky, the heavens; the void, nothingness.

A giant void; nothingness

Often as aether and more fully as luminiferous aether: a substance once thought to fill all unoccupied space that allowed electromagnetic waves to pass through it and interact with matter, without exerting any resistance to matter or energy; its existence was disproved by the 1887 Michelson–Morley experiment and the theory of relativity propounded by Albert Einstein (1879–1955).

An atmospheric movement; a breeze or wind.

The atmosphere or space as a medium for broadcasting radio and television signals; also, a notional space through which Internet and other digital communications take place; cyberspace.

(Sports) A height achieved by a jump or as part of an airborne maneuver, as in skateboarding or snowboarding

A particular quality created by or surrounding an object, person, or place; an atmosphere, an aura.

Aircraft

Diethyl ether (C4H10O), an organic compound with a sweet odour used in the past as an anaesthetic.

Public utterance; vent

Any of a class of organic compounds containing an oxygen atom bonded to two hydrocarbon groups.

The medium of broadcast radio or television

(uncountable) Starting fluid.

A manner of behaving that conveys an impression

To viciously humiliate or insult.

A distinctive quality or appearance; an aura

A medium of great elasticity and extreme tenuity, once supposed to pervade all space, the interior of solid bodies not excepted, and to be the medium of transmission of light and heat; hence often called luminiferous ether. It is no longer believed that such a medium is required for the transmission of electromagnetic waves; the modern use of the term is mostly a figurative term for empty space, or for literary effect, and not intended to imply the actual existence of a physical medium. However. modern cosmological theories based on quantum field theory do not rule out the possibility that the inherent energy of the vacuum is greater than zero, in which case the concept of an ether pervading the vacuum may have more than metaphoric meaning.

The general environment or condition, as in attitudes and ideas

Supposed matter above the air; the air itself.

Airs Affected behavior; affectation

A light, volatile, mobile, inflammable liquid, (C2H5)2O, of a characteristic aromatic odor, obtained by the distillation of alcohol with sulphuric acid, and hence called also sulphuric ether. It is a powerful solvent of fats, resins, and pyroxylin, but finds its chief use as an anæsthetic. Commonly called ethyl ether to distinguish it from other ethers, and also ethyl oxide.

A melody or tune, especially in the soprano or tenor range.

A colorless volatile highly inflammable liquid formerly used as an inhalation anesthetic

A solo with or without accompaniment.

Any of a class of organic compounds that have two hydrocarbon groups linked by an oxygen atom
