← ScienceWhich risk increases with isothermal expansion inefficiencies during a Carnot cycle?
A)Decreased net work output✓
B)Increased system thermal mass
C)Reduced heat transfer reversibility
D)Elevated isochoric heat capacity
💡 Explanation
Inefficiencies during isothermal expansion reduce the net work. This is because friction converts some work into heat, increasing entropy generation rather than useful output; therefore the work diminishes rather than other thermal properties changing.
