Gas Thermometer (Noun)
Meaning
Thermometer that measures temperature by changes in the pressure of a gas kept at constant volume.
Classification
Nouns denoting man-made objects.
Examples
- The gas thermometer is more complex and less commonly used than liquid thermometers due to its bulkier setup and increased cost.
- A constant-volume gas thermometer uses the relationship between gas pressure and temperature to measure temperature.
- To reduce errors, gas thermometers should be calibrated by comparing the readings against a trusted measurement standard.
- The gas thermometer is known for being relatively accurate, even at extremely low temperatures, where conventional thermometers tend to fail.
- Historically, the development of the gas thermometer helped scientists discover the absolute temperature scale, also known as the Kelvin scale.
