← ScienceDuring rapid expansion in a Carnot engine, which mechanism reduces overall engine efficiency?
A)Increased internal irreversibilities of the process✓
B)Decreased thermal contact with reservoir
C)Enhanced heat transfer to surroundings
D)Reduced entropy of heat input
💡 Explanation
Increased internal irreversibilities reduces engine efficiency because it deviates from the idealized reversible Carnot cycle isothermal expansion phase, generating entropy, therefore limiting its efficiency rather than alternatives, as the Carnot cycle's idealized process is isentropic.
