Question:

The efficiency of an ideal heat engine working between the freezing point and boiling point of water, is :

Options:

26.8 %

20 %

12.5 %

6.25 %

Correct Answer:

26.8 %

Explanation:

Efficiency of heat engine : $\eta = (1 - \frac{T_2}{T_1})$

T₂ : Sink Temperature = 273 K ;

T₁ : Source Temperature = 373 K ;

$\eta$ % = 26.8 %
