← ScienceWhich risk increases when a Carnot engine cycles far from equilibrium?
A)Reduced energy conversion efficiency✓
B)Increased mechanical stress internally
C)Decreased operational temperature range
D)Elevated super-adiabatic temperature gradients
💡 Explanation
Increased heat transfer irreversibility causes reduced efficiency because entropy generation rises significantly; therefore the engine performs worse, rather than experiencing mechanical failures or facing different temperature restrictions, where quasistatic processes minimize losses via isothermal expansion/compression.
