The thermometric property in the Kelvin scale is _______
a. Temperature (T)
b. Work energy (W)
c. Heat energy (Q)
d. all of the above
Correct Answer: c. Heat energy (Q)
Explanation: 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.
Explanation: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.
