B. Efficiency less than the efficiency of a Carnot engine operating between the same two temperatures.
C. Efficiency equal to
D. Efficiency less than
Choose the correct answer from the options given below
View answer and explanation
Correct option: C
B and D only
Option C (B and D only) is correct because the efficiency of any engine operating between two temperatures is less than that of a Carnot engine, and the Carnot efficiency between 0°C and 100°C is less than 27%.
