A Carnot engine is operating between a hot body and cold body maintained at temperature $T_{1}$ and $T_{2}$ respectively. Consider the following three cases

Case I : The temperature of the hot body is changed to $T_{1} + Δ T$ and cold body is at $T_{2}$

Case II : The temperature of the hot body is at $T_{1}$ and cold body is changed to $T_{2} + Δ T$

Case III : The temperature of the hot body is

A Carnot engine whose low-temperature reservoir is at

350 K

has an efficiency of

50 %

. It is desired to increase this to

60 %

. If the temperature of the low-temperature reservoir remains constant, then the temperature of the high-temperature reservoir must be increased by how many degrees?
