What factors exclusively determine the Carnot efficiency, according to the derived formula?
Answer
The absolute temperatures of the high-temperature source ($T_H$) and the low-temperature sink ($T_C$).
The Carnot efficiency ($ ext{eta}_{ ext{Carnot}} = 1 - T_C/T_H$) is determined solely by the ratio of the absolute temperatures of the hot source and the cold sink, independent of the working fluid or cycle details.
