Liquid air is air that has been cooled to very low temperatures (cryogenic temperatures), so that it has condensed into a pale blue mobile liquid. To protect it from room temperature, it must be kept in a vacuum insulated flask. Liquid air can absorb heat rapidly and revert to its gaseous state. It is often used for condensing other substances into liquid and/or solidifying them, and as an industrial source of nitrogen, oxygen, argon, and other inert gases through a process called air separation. Liquid air is also replacing liquid nitrogen for theatrical smoke and fog effects.

Famous quotes containing the words liquid and/or air:
““Awake,
My fairest, my espoused, my latest found,
Heaven’s last best gift, my ever new delight,
Awake, the morning shines, and the fresh field
Calls us: we lose the prime, to mark how spring
Our tended plants, how blows the citron grove,
What drops the myrrh and what the balmy reed,
How nature paints her colors, how the bee
Sits on the bloom extracting liquid sweet.””
—John Milton (1608–1674)
“Up from the South at break of day,
Bringing to Winchester fresh dismay,
The affrighted air with a shudder bore,
Like a herald in haste, to the chieftain’s door,
The terrible grumble, and rumble, and roar,
Telling the battle was on once more,
And Sheridan twenty miles away.”
—Thomas Buchanan Read (1822–1872)
