Question

Efficiency of Carnot engine working between T₁ (hot) and T₂ (cold) is:
  1. A
    1 − T₁/T₂
  2. B
    1 − T₂/T₁
    Correct
  3. C
    T₂/T₁
  4. D
    T₁/T₂

Correct answer

1 − T₂/T₁

Explanation

η_Carnot = 1 − T₂/T₁ (T in Kelvin). This is the maximum possible efficiency for any engine operating between these temperatures.
