Which outcome occurs when a Sterling engine approaches Carnot efficiency?

💡 Explanation

Energy transfer must be infinitesimally slow for idealized, reversible isothermal processes to occur at Carnot efficiency because isothermal processes need essentially zero temperature gradients to uphold reversibility; therefore, the engine becomes unrealistically slow rather than operating efficiently or transitioning to different thermodynamic regimes.
