← ScienceWhich outcome impairs Carnot engine performance during rapid cycling?
A)Isothermal process deviates due to irreversibilities✓
B)Adiabatic process achieves idealized expansion
C)Engine speed matches molecular velocities
D)Engine exploits quantum entanglement efficiently
💡 Explanation
Deviation arises because finite-time heat transfer initiates irreversibilities, hindering isothermal expansion that is vital for optimizing high-efficiency conversions during operation; therefore, performance drops, rather than benefiting from adiabatic processes as in ideal conditions.
