- The Kelvin scale exists because it is an absolute measure of temperature12. Proposed by British scientist William Thomson (Lord Kelvin) in 1848, it is independent of the properties of specific substances and directly related to kinetic energy and volume3. The Kelvin scale was adopted as the base unit for thermodynamic temperature by the General Conference on Weights and Measures in 19544. Unlike Celsius and Fahrenheit, which have arbitrary zero points, Kelvin begins at absolute zero, making it a natural unit for measuring temperature12345.Learn more:✕This summary was generated using AI based on multiple online sources.

Changes in Celsius or Fahrenheit are not directly related to kinetic energy or volume because these scales do not begin at zero. Scientists use the Kelvin scale because it is an absolute measure of temperature and is directly related to kinetic energy and volume.byjus.com/chemistry/kelvin-temperature-scale/Temperature is defined in terms of the average energy of particles in a system, and Kelvin is directly proportional to that -- the zero in the Kelvin scale corresponds to absolute zero, and not any arbitrary temperature, and Kelvin is the 'natural' unit to measure temperature.www.physlink.com/education/askexperts/ae129.cfmIn 1848, British mathematician and scientist William Thomson (also known as Lord Kelvin) proposed an absolute temperature scale, which was independent of the properties of a substance like ice or the human body. He suggested that the range of possible temperatures in the universe far exceeded those proposed by Celsius and Fahrenheit.www.livescience.com/temperature.htmlThe kelvin has been the preferred scale for scientists since 1954, when the General Conference on Weights and Measures (CGPM) — an international organization that makes decisions about measurement standards — adopted the kelvin (K) as the base unit for thermodynamic temperature.www.nist.gov/si-redefinition/kelvin-historyThe Kelvin unit was formed due to the inconsistent reference points of the Fahrenheit and Celsius temperature scales. After the discovery of the ideal gas relationship, it was instead suggested to use the limit of the Ideal gas law as pressure approaches zero, which would act as a consistent, but hypothetical reference point for temperature.physics.stackexchange.com/questions/607137/whe…

The kelvin, symbol K, is the base unit of measurement for temperature in the International System of Units (SI). The Kelvin scale is an absolute temperature scale that starts from 0 K, the coldest possible temperature (absolute zero), then rises by exactly 1 K for each 1 °C. The Kelvin scale was designed to be … See more
