Solution

The correct option is C Zeroth Law of Thermodynamics
Answer: A
The zeroth law of thermodynamics justifies the use of suitable thermodynamic systems as thermometers to provide such a labeling, which yield any number of possible emprical temperature scales, and justifies the use of the second law of thermodynamics to provide an absolute, or thermodynamic temperature scale. Such temperature scales bring additional continuity and ordering (i.e., "hot" and "cold") properties to the concept of temperature.
