Definition

Noun: * A cryogenic liquid form of the element oxygen. It is a pale blue, highly magnetic fluid produced by cooling gaseous oxygen below its boiling point. Its primary industrial use is as a powerful oxidizing agent.

Usage

"Liquid oxygen" is an uncountable noun. It refers to the substance in its bulk state, not individual units. It is often abbreviated as LOX in technical contexts, especially aerospace engineering.

Examples

• The rocket's first stage is fueled by a combination of liquid oxygen and kerosene.
• Handling liquid oxygen requires specialized equipment due to its extremely low temperature.
• The laboratory stored the biological samples in liquid oxygen.

Advanced Usage

• LOX is the standard acronym in rocketry and industrial applications.
  • The new engine design improves the mixing ratio of fuel and LOX.

Variants and Related Words

• LOX: The standard acronym for liquid oxygen.
• Cryogenic fluid: A general term for liquids at extremely low temperatures, which includes liquid oxygen.
• Oxidizer / Oxidizing agent: A substance that supports combustion, describing the primary function of liquid oxygen in propulsion.

Synonyms

• LOX (acronym)
• Cryogenic oxygen

Notes on Meaning

The term specifically denotes oxygen in a condensed, liquid state distinguished by its physical properties (very low temperature, pale blue color, paramagnetism). Its defining characteristic in application is its role as a high-potential oxidizer, not merely as a form of oxygen.

Noun

1. a bluish translucent magnetic liquid obtained by compressing gaseous oxygen and then cooling it below its boiling point; used as an oxidizer in rocket propellants
