compressed gas

A worker carefully checks the valve on a tank of compressed gas.

Definition
  1. Noun:
    • A gas that is kept under high pressure, typically in a cylinder or tank. This high pressure reduces the gas's volume, allowing a large amount to be stored in a relatively small container. Compressed gases are used for various purposes, including as propellants, fuels, and in industrial processes.
Examples of Usage
  • Noun:
    • The firefighters used a tank of compressed gas to fill the air cylinders for their breathing apparatus.
    • Many aerosol products, like spray paint, use a compressed gas to push the liquid out of the can.
    • The laboratory stores several types of compressed gas, including nitrogen and helium, for experiments.
Advanced Usage
  • "Compressed gas cylinder": A strong metal container designed to safely hold gas under high pressure.
    • Always secure a compressed gas cylinder in an upright position when storing or transporting it.
  • "Compressed gas propellant": Specifically refers to a compressed gas used to create thrust or force something forward.
    • The model rocket uses a compressed gas propellant, such as carbon dioxide, for launch.
Variants and Related Words
  • Compress (verb): To press or squeeze something so that it takes up less space.
    • The machine compresses the trash into dense blocks.
  • Compression (noun): The action of compressing or the state of being compressed.
    • Data compression reduces the file size for easier storage.
  • Pressurized gas: A very close synonym, often used interchangeably in technical contexts.
Synonyms
  • Pressurized gas
  • High-pressure gas
Related Phrases
  • Handle with care: A common warning label found on containers of compressed gas due to their potential hazard.
    • The shipment of compressed gas was marked "handle with care".
  • Inert gas: A type of non-reactive gas (e.g., argon, helium) that is often stored and used in a compressed form.
    • Welding with an inert gas like argon requires a tank of compressed gas.
Related Idioms
  • Under pressure: While not exclusive to gases, this idiom meaning "stressed" originates from the physical state of compression.
    • The team was under pressure to finish the project on time, much like a compressed gas in a tank.
