compressed gas
Học thuậtThân thiện
Definition
- 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.
