What is the thermometric property Kelvin scale? - Thermodynamics

Q.  The thermometric property in the Kelvin scale is _______
- Published on 20 Aug 15

a. Temperature (T)
b. Work energy (W)
c. Heat energy (Q)
d. all of the above

ANSWER: Heat energy (Q)
Consider the following diagram of heat engine which has sink at triple point of water. The Carnot heat engine takes heat Q from source at temperature T and produce work W and rejects heat Qt at sink which is at triple point of water.

According to the definition of Kelvin scale,

Q/Qt = T/ Tt

T = 273.16 (Q/Qt)

From the above equation it is clear that Q that is heat plays a role of thermometric property. The amount of heat supply changes with change is temperature.
