← ScienceWhich consequence results when exceeding power limits during an adiabatic cycle?
A)Increased irreversibility diminishes cycle efficiency✓
B)Isothermal phases experience decreased heat
C)Total entropy change will negligibly decrease
D)Piston compression increases, averting temperature change
💡 Explanation
Exceeding power limits causes increased irreversibility because the system deviates further from thermodynamic equilibrium; this enhances entropy generation via frictional losses leading to decreased efficiency therefore efficiency drops rather than alternative changes, because of reduced equilibrium approximations.
