Final answer:
To convert a temperature of 14K to degrees Celsius, subtract 273.15, resulting in -259.15°C.
Step-by-step explanation:
The temperature in Kelvin (K) is a standard unit of temperature in the scientific community, particularly used in physics and chemistry. To convert the temperature from Kelvin to degrees Celsius (°C), one subtracts 273.15 from the Kelvin temperature. Thus, for a temperature of 14K, the conversion in degrees Celsius is calculated by subtracting 273.15 from 14, which results in -259.15°C.
The kelvin, symbol K, is a unit of measurement for temperature. The Kelvin scale is an absolute scale, which is defined such that 0 K is absolute zero and a change of thermodynamic temperature T by 1 kelvin corresponds to a change of thermal energy kT by 1.380649×10−23 J. The Boltzmann constant k = 1.380649×10−23 J⋅K−1 was exactly defined in the 2019 redefinition of the SI base units such that the triple point of water is 273.16±0.0001 K.
The kelvin is the base unit of temperature in the International System of Units (SI), used alongside its prefixed forms. It is named after the Belfast-born and University of Glasgow-based engineer and physicist William Thomson, 1st Baron Kelvin (1824–1907).
