The maximum possible efficiency of a heat engine is ...........
  • A
    $100 \%$
  • B
    $\frac{T_1}{T_2}$
  • C
    $\frac{T_1}{T_2}+1$
  • ✓
    Dependent upon the temperature of source $\left(T_1\right)$ and $\operatorname{sink}\left(T_2\right)$ and is equal to $\left(1-\frac{T_2}{T_1}\right)$
✓

Answer

Correct option: D.
Dependent upon the temperature of source $\left(T_1\right)$ and $\operatorname{sink}\left(T_2\right)$ and is equal to $\left(1-\frac{T_2}{T_1}\right)$
d
(d)

$\eta=1-\frac{T_2}{T_1}$

So it depends on source and sink temperature.
