Here is my weekly weather quiz question for the last timer. What is the “Kelvin Temperature Scale? Here is the correct answer.  The Kelvin Temperature Scale is an absolute temperature scale in which a change of 1 Kelvin equals a change of 1 degree Celsius; 0ºK is the lowest temperature on the Kelvin scale. The freezing point of water is +273ºK (Kelvin) and the boiling point of +373ºK. It is used primarily for scientific purposes. It is also known as the Absolute Temperature Scale.
