← ScienceWhich inefficiency increases when a Carnot engine's temperature difference shrinks?
A)Heat rejected to cold resevoir✓
B)Friction within the piston seals
C)Rate of fuel combustion increases
D)Radiative heat loss intensifies quickly
💡 Explanation
Waste heat increases because the Carnot cycle's efficiency depends on the temperature gradient; according to the Carnot efficiency equation, a smaller temperature difference means lower efficiency, creating more waste energy. Therefore, more heat will be rejected at the end rather than converted to work.
