You want to increase the efficiency of a Carnot engine by altering the temperature of either of the reservoirs by a temperature of ΔT. Which of the following will produce the greatest increase in efficiency?
A) Increasing the temperature of the hot reservoir by ΔT
B) Increasing the temperature of the cold reservoir by ΔT
C) Decreasing the temperature of the hot reservoir by ΔT
D) Decreasing the temperature of the cold reservoir by ΔT
E) Option A or D, because the temperature change ΔT is the same for either case
F) Option B or C, because the temperature change ΔT is the same for either case
