What is the value of triple point?- Thermodynamics
Q. Arbitrarily, the value of triple point is taken as- Published on 20 Aug 15a. 0 K
b. 273.16 oC
c. 273.16 K
d. none of the above
ANSWER: 273.16 K
As the heat is absorbed and rejected respectively by the Carnot engine operating between two reservoirs of different temperatures T1 and T2, these two temperatures on the Kelvin scale feature the same relationship with each other. The heat absorbed and the heat rejected can be measured during two reversible isothermal and two reversible adiabatic processes in a Carnot engine. The triple point of water is used in defining the Kelvin temperature scale. The triple point temperature of water is taken arbitrarily as 273.16 K
