Thermodynamic Absolute temperature reading of zero is of particular importance for the third law of thermodynamics.

FactSnippet No. 975,848

Thermodynamic Absolute temperature is of importance in thermodynamics because it is defined in purely thermodynamic terms.

FactSnippet No. 975,849

Thermodynamic Absolute temperature was rigorously defined historically long before there was a fair knowledge of microscopic particles such as atoms, molecules, and electrons.
