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

Related Phrases

Related Idioms

• Under pressure: While not exclusive to gases, this idiom meaning "stressed" originates from the physical state of compression.
