Kelvin: meaning, definitions and examples
๐ก๏ธ
kelvin
[ หkษlvษชn ]
temperature scale
Kelvin is a unit of temperature measurement in the International System of Units (SI). It is named after the Scottish physicist William Thomson, 1st Baron Kelvin, who proposed this absolute temperature scale. The Kelvin scale starts at absolute zero, the point at which all molecular motion ceases. Each increment on the Kelvin scale is equivalent to one degree Celsius, making it essential for scientific calculations, particularly in physics and engineering.
Examples of usage
- The water boils at 373.15 Kelvin.
- Absolute zero is 0 Kelvin.
- The temperature of the star is around 5000 Kelvin.

Etymology
The term 'Kelvin' was established in the 19th century, derived from the name of the Scottish physicist William Thomson, who was honored with the title of Lord Kelvin in 1892. The Kelvin scale was introduced as part of a broader movement in science to create an absolute temperature scale that would enhance the precision of thermodynamic calculations. It was chosen because it provides a reliable reference point for thermal energy. When Lord Kelvin formulated this scale in 1848, he suggested that 0 K be defined as the temperature at which the entropy of a perfect crystal reaches its minimum value; this is known as absolute zero. The Kelvin scale is commonly used in scientific fields, particularly in thermodynamics and physical chemistry, where temperature measurements are crucial to understanding the behavior of physical systems.
