Which mechanism limits the Carnot engine's real-world efficiency?

💡 Explanation

Irreversible heat transfer generates entropy, increasing wasted energy; therefore, efficiency decreases because the Carnot cycle assumes perfectly reversible processes, rather than heat leaks or friction common in operation.
