Triple Point Of Water
The triple point of water is the temperature and pressure at which water can coexist in solid, liquid, and gaseous states in thermodynamic equilibrium.
History/Origin
The triple point of water was first precisely defined in the 19th century and has since been used as a fundamental fixed point in temperature measurement, notably in the International Temperature Scale (ITS-90).
Current Use
The triple point of water serves as a standard calibration point for thermometers and is used to define the Kelvin temperature scale, with the unit symbol TPW representing this specific fixed point in temperature measurement.
Reaumur
The Reaumur is a temperature scale where 0°r is the freezing point of water and 80°r is the boiling point under standard conditions.
History/Origin
Developed by René Antoine Ferchault de Réaumur in 1730, it was widely used in Europe for scientific and industrial purposes before being largely replaced by Celsius and Fahrenheit scales.
Current Use
The Reaumur scale is now rarely used, primarily in some regions of France and historical contexts, with most temperature measurements adopting Celsius or Fahrenheit.
