Value of absolute temperature on the Celsius scale is equal to -273.15 oC.
Kelvin scale is the most commonly used temperature scale in science. It is an absolute temperature scale defined to have 0 K at the lowest possible temperature, called absolute zero. The freezing and boiling points of water on this scale are 273.15 K and 373.15 K, respectively. Unlike other temperature scales, the Kelvin scale is an absolute scale.
- Absolute zero is the lowest possible temperature where nothing could be colder and no heat energy remains in a substance.
- 0K on the Kelvin scale, which is a thermodynamic (absolute) temperature scale.–273.15 degrees Celsius on the Celsius scale.
