The efficiency of a Carnot engine operating between 100 $\degree$C and 0 $\degree$C is most nearly:

Question

Quizplus · Accepted Answer

The efficiency of a Carnot engine is given by the formula:
Efficiency = 1 - (T2/T1)
where T1 is the absolute temperature at the higher temperature reservoir (in Kelvin) and T2 is the absolute temperature at the lower temperature reservoir (in Kelvin).

Converting the temperatures given in Celsius to Kelvin, we get:

T1 = 373 K
T2 = 273 K

Plugging in the values, we get:

Efficiency = 1 - (273/373)
Efficiency = 1 - 0.731
Efficiency = 0.269 or 26.9%

Therefore, the closest choice is C, 27%.
