The Kelvin scale is based on the Celsius scale, with 0 K being absolute zero, at which point all matter would theoretically have zero entropy. Negative temperatures are a relative concept, meaning that a system's temperature is considered negative when its entropy is lower than absolute zero. The concept may seem counterintuitive, but think of it like a see-saw: if the system's energy is lower than its surroundings, its temperature appears negative on the Kelvin scale.

  • Negative temperatures, in the sense of absolute temperature, are not found naturally. However, systems can exhibit a kind of "negative temperature" through quantum phenomena.
    • The Kelvin scale is used to measure temperatures above absolute zero, the theoretical minimum temperature at which all molecular motion ceases. Unlike the Celsius and Fahrenheit scales, which are based on the freezing and boiling points of water, the Kelvin scale is an absolute temperature scale that has a natural zero point. The Kelvin scale is used in various scientific and industrial applications, where precision and accuracy are crucial.
