Kelvintemperature

Kelvin temperature is a thermodynamic temperature scale where zero Kelvin, denoted as 0 K, is absolute zero. At absolute zero, particles have minimal thermal motion, and theoretically, no more heat can be removed from a system. The Kelvin scale is an SI base unit, meaning it is one of the fundamental units of measurement in the International System of Units.

Unlike Celsius or Fahrenheit, the Kelvin scale does not use degrees. Instead, it is a direct measure of kinetic energy. The size of one Kelvin unit is equivalent to the size of one degree Celsius. This means that a change of 1 Kelvin is the same as a change of 1 degree Celsius. The conversion between Celsius and Kelvin is straightforward: Kelvin = Celsius + 273.15.

The Kelvin scale is widely used in scientific fields, particularly in physics, chemistry, and astronomy. It is essential for expressing temperatures in scientific calculations and for describing phenomena at very low temperatures, such as superconductivity, or very high temperatures, such as those found in stars. The absence of negative values in the Kelvin scale makes it convenient for thermodynamic calculations where negative absolute temperatures are not physically meaningful. Absolute zero was first theorized by Lord Kelvin in the mid-19th century and is a fundamental concept in thermodynamics.
