Meaning and Definition
Air that has been cooled and compressed to the point where it becomes a clear, very cold liquid.
A cryogenic fluid produced by the fractional distillation of atmospheric air, used primarily in industrial and scientific applications for its extremely low temperature properties.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning or usage. Spelling of related terms may follow regional conventions (e.g., 'liquidise' vs. 'liquefy' in verbs, but 'liquefaction' is standard in both for this process).
Connotations
Purely technical and neutral in both varieties.
Frequency
Equally low frequency in both, confined to engineering, chemistry, and industrial contexts.

FAQ
Frequently Asked Questions
Yes, it is extremely cold (cryogenic) and can cause severe frostbite on contact with skin. It also requires careful handling as it can cause pressure build-up in sealed containers.
It is primarily a mixture of liquid nitrogen (about 78%) and liquid oxygen (about 21%), with traces of other gases like argon, mirroring the composition of the atmosphere.
No, you cannot breathe liquid air. It would cause immediate freezing and damage to the lungs. The concept of breathing a liquid is theoretical and involves specially oxygenated fluids, not liquid air.
You are unlikely to encounter it in daily life. It is used in industrial settings, research laboratories, and sometimes in demonstrations of cryogenics or energy storage technology.
Air that has been cooled and compressed to the point where it becomes a clear, very cold liquid.
Liquid air is usually technical / scientific in register.
