← ScienceWhich limitation arises in a theoretical Carnot heat engine experiencing extremely high thermal gradients?
A)Increased irreversible heat transfer✓
B)Decreased isothermal heat absorption
C)Reversible adiabatic compression failure
D)Reduced mechanical work extraction
💡 Explanation
When a Carnot engine operates with very high temperature differences, it faces augmented temperature gradients, causing increased irreversible heat transfer, because high thermal gradients accelerate entropy generation. Therefore, the system can not maintain theoretical reversibility, rather than optimal performance expected in idealized conditions.
