Question
In which case will the efficiency of a Carnot cycle be higher, when the hot body temperature is increased by ΔT or when the cold body temperature is decreased by the same magnitude?
Options
A.Same in both.
B.On decreasing the temperature of cold body.
C.On increasing the temperature of hot body.
D.Depends on the initial temperature of cold and hot bodies.
Solution
$\left( 1 - \frac{T_{C} - \Delta T}{T_{H}} \right) > \left( 1 - \frac{T_{C}}{T_{H} + \Delta T} \right)$
