Examples of barometer in the following topics:
-
- Early barometers were used to measure atmospheric pressure through the use of hydrostatic fluids.
- Pressure, as determined by hydrostatic barometers, is often measured by determining the height of the liquid in the barometer column, thus the torr as a unit of pressure, but can be used to determine pressure in SI units .
- Hydrostatic based barometers most commonly use water or mercury as the static liquid.
- Another type of barometer is the aneroid barometer, which consists of a small, flexible sealed metal box called an aneroid cell.
- The concept of determining pressure using the fluid height in a hydrostatic column barometer
-
- Torr and millimeters of mercury (mm Hg, defined as a one millimeter difference in the height of a mercury barometer at 0°C) are nearly equivalent.
- manometer barometer mmhg atm kpa units kinetic molecular theory
-
- For this reason GDP per capita may not necessarily be a barometer for the quality of life in a given country.
-
- Mercury is used in thermometers, barometers, manometers, float valves, mercury switches, and other devices.
-
- This may be seen between mercury and glass in barometers and thermometers.
-
- Southern slaveowners held that restricting slavery
would violate the principle of states' rights whereas many Northerners believed
popular sovereignty should serve as a barometer for the expansion of slavery,
and some even believed it should be abolished completely.
-
- In addition, the foreign exchange market is one of the most traded and liquid instruments in the financial world, and serves as a barometer of broader financial market conditions and risk appetite.
-
- Thermoscopes also served as barometers (which measure pressure).
-
- Invention of tools that deepened the understating of sciences, including mechanical calculator,
steam digester (the forerunner of the steam engine), refracting and reflecting telescopes, vacuum pump, or mercury barometer.
