| Liquid air sounds like a contradiction in terms but in fact, it's
not. Air, when cooled enough (-321°F or -196°C), condenses
into a liquid and when cooled further even freezes solid. We're familiar
with this phenomenon in the case of water: steam condenses to liquid
water that freezes to ice. Or, to put it the other way, ice melts to
form water at 0°C and boils to produce steam at 100°C. (These temperatures change as the pressure changes. At
high altitudes, for example, water boils at a lower temperature because of the
lower air pressure.) |
