Air 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 air thermometer was invented by Guillaume Amontons in the early 18th century to measure temperature by changes in the pressure of a gas kept at constant volume.
- To measure temperature, the air thermometer uses a gas with a constant volume that expands or contracts with changes in temperature, affecting the pressure.
- An air thermometer typically consists of a sealed container filled with a gas, such as air or nitrogen, connected to a pressure gauge to measure the changes in pressure.
- In contrast to mercury thermometers, air thermometers do not rely on the expansion and contraction of a liquid to measure temperature.
- Air thermometers have several advantages, including the ability to measure temperatures over a wide range and their relatively low cost compared to other types of thermometers.
