kelvin
Kelvin (noun) – Meaning, Examples & Etymology
IPA:

What does kelvin mean?
The standard unit of temperature in the International System of Units (SI).
"Absolute zero is defined as 0 Kelvin."
Detailed Meaning of Kelvin
It is named after William Thomson, also known as Lord Kelvin, who was a British physicist and mathematician. The Kelvin scale is based on the absolute zero of temperature, which is the theoretical temperature at which all molecular motion ceases. In the Kelvin scale, this temperature is defined as 0K, while the melting point of ice is 273.15K, and the boiling point of water is 373.15K. The Kelvin scale is used extensively in scientific and engineering fields, especially in fields such as physics, chemistry, and astronomy, where high precision and accuracy are required in temperature measurements.
Example Sentences for Kelvin
1. Kelvin is the unit of measurement for temperature in the International System of Units (SI).
2. Absolute zero, the lowest possible temperature, is defined as 0 Kelvin.
3. Kelvin is often used in scientific and technical fields for precise temperature measurements.
4. The Kelvin scale is based on the Celsius scale, with 0 Kelvin equal to -273.
5. 15 degrees Celsius.
6. Kelvin is named after the Scottish physicist William Thomson, also known as Lord Kelvin.
Origin and Etymology of Kelvin
The noun 'kelvin' is a tribute to the Scottish physicist William Thomson, 1st Baron Kelvin, who made significant contributions to the field of thermodynamics and the study of heat. The term 'kelvin' as a unit of temperature was established to honor his work. It was adopted in the International System of Units (SI) as the standard unit of temperature. The use of the name 'kelvin' to represent this unit dates back to the 20th century, and it serves as a fitting recognition of Lord Kelvin's pioneering contributions to the understanding of temperature and thermodynamics.
