← ScienceWhich inefficiency increases when rapid Carnot expansion occurs?
A)Isothermal gas heat transfer lag✓
B)Adiabatic enclosure thermal conduction
C)Regenerator imperfect heat exchange
D)Mechanical piston-cylinder frictional losses
💡 Explanation
Temperature gradients drive losses; rapid expansion reduces the time for isothermal heat transfer, therefore temperature differences cause deviation from ideal Carnot conditions, rather than conductive losses, regenerator problems, or simple friction.
