← ScienceWhich risk increases because of unavoidable limitations in a Carnot engine?
A)Excessive energy dissipation by friction✓
B)Thermal runaway causing engine failure
C)Incomplete fuel combustion products formilng
D)Decreased material strength from cyclic loading
💡 Explanation
Increased energy dissipation happens due to **irreversibility**, because real-world conditions are not perfectly reversible, and entropy increases. Therefore, friction produces energy dissipation, rather than the explosion of materials or chemical imbalances, despite its high temperature
