Science

Which risk increases when a Carnot engine's exhaust backs up, raising the low-temperature reservoir's thermal capacity?

A)Increased power output instability
B)Inefficient heat transfer decreases
C)Excessive material contraction occurs
D)Refrigerant degradation is accelerated

💡 Explanation

Increased thermal capacity causes smaller temperature gradients, making the heat transfer inefficient and power output unstable because the Carnot cycle dictates that efficiency relies on the temperature difference; therefore, the power declines, rather than material failure.
