Topic: Thermodynamics

Carnot cycle has maximum efficiency for

  • A. Petrol engine
  • B. Diesel engine
  • C. Reversible engine
  • D. Irreversible engine

Answer: C. Reversible engine

Explanation: According to Carnot's theorem, no engine operating between two given temperature limits can be more efficient than a completely reversible engine operating between the same limits. Thus, the Carnot cycle has maximum efficiency for a reversible engine.
