A Carnot engine whose heat sinks at $\displaystyle 27$°C, has an efficiency of $\displaystyle 25$%. By how many degrees should the temperature of the source be changed to increase the efficiency by $\displaystyle 100 \%$ of the original efficiency ?
Official answer
(2)
Increases by $\displaystyle 200$°C
