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.
Kelvin
The kelvin (K) is the base unit of temperature in the International System of Units (SI), defined as 1/273.16 of the thermodynamic temperature of the triple point of water.
History/Origin
The kelvin was established in 1848 by Lord Kelvin (William Thomson) as a temperature scale based on absolute zero, replacing earlier thermodynamic temperature scales. It was officially adopted as an SI base unit in 1960.
Current Use
The kelvin is used worldwide in scientific and engineering contexts to measure thermodynamic temperature, especially in physics, chemistry, and related fields, providing a standard for temperature measurement without negative values.
