what is the kelvin scale for temperature
Kelvin temperature scale. Kelvin temperature scale, a temperature scale having an absolute zero below which temperatures do not exist. Absolute zero, or 0Â°K, is the temperature at which molecular energy is a minimum, and it corresponds to a temperature of - 273.15Â° on the Celsius temperature scale.hen writing temperatures in the Kelvin scale, it is the convention to omit the degree symbol and merely use the letter K. The temperature scale is named after the British mathematician and physicist William Thomson Kelvin, who proposed it in 1848.
