Unlike the Celsius or Fahrenheit scales—which were originally based on the freezing point of water or human body temperature—absolute temperature is tied directly to the fundamental laws of physics and the motion of atoms. 1. The Concept of Absolute Zero
At its core, temperature is a measure of the average kinetic energy of the particles in a substance. As things get colder, their atoms slow down. Absolute zero ( absolute temperature
is the absolute floor, there are no negative values. This simplifies complex mathematical models. absolute temperature
