What is the thermometric property Kelvin scale? - Thermodynamics
Q. The thermometric property in the Kelvin scale is _______- Published on 20 Aug 15a. 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 Q
t at sink which is at triple point of water.
According to the definition of Kelvin scale,
Q/Q
t = T/ T
tT = 273.16 (Q/Q
t)
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.
