Thermodynamics Second Law of Thermodynamics and Entropy Performance of Heat Engines and Reversed Heat Engines
One reversible heat engine operates between 1600 K and T2 K and another reversible heat engine operates between T2 K and 400 K. If both the engines have the same thermal efficiency, the temperature T2 is,
1
800 K
2
1000 K
3
1200 K
4
1400 K
