Which risk increases when the Carnot engine operates isothermally?

💡 Explanation

Component overheating will be exacerbated because isothermal operation requires high thermal conductivity, causing heat to spread more freely, increasing localized hot spots due to imperfect heat transfer. Therefore, overheating risk is greater, rather than improved cooling or more efficient conversion.
