n =1-( T L / T H ) At constant T L , efficiency increases with the increase in T H .

Q. A number of cannot engines are operated at identical cold reservoir temperatures $(T_{L})$ . However, their hot reservoir temperatures are kept different. A graph of the efficiency of the engines versus hot reservoir temperature $(T_{H})$ is plotted. The correct graphical representation is

$n = 1 - \frac{T _{L}}{T _{H}}$ At constant $T_{L}$ , efficiency increases with the increase in $T_{H}$ .

Q. A number of cannot engines are operated at identical cold reservoir temperatures (TL​). However, their hot reservoir temperatures are kept different. A graph of the efficiency of the engines versus hot reservoir temperature (TH​) is plotted. The correct graphical representation is

n=1−TH​TL​​ At constant TL​, efficiency increases with the increase in TH​.
