Answer: 2260000 J.
- A 2260 J
- B 22600 J
- C 226000 J
- D 2260000 J
Correct answer: D. 2260000 J
Explanation: Q = m x L = 1 x 2.26 x 10<sup>6</sup> = 2.26 x 10<sup>6</sup> J = 2,260,000 J.
The Carnot cycle alternates two isothermal steps (heat absorbed at TH, released at TC) with two adiabatic steps (no heat exchange); the enclosed loop area equals the net work output, and η = 1−TC/TH is the maximum possible efficiency between those two temperatures.
