Which outcome arises from isothermally compressing a Carnot heat engine working fluid beyond minimum volume at constant temperature?

A)Reduced heat transfer to cold reservoir
B)Conversion of compression work into heat
C)Isentropic expansion phase is bypassed
D)Net work produced during the cycle ceases

💡 Explanation

When isothermally compressing a working fluid beyond the design minimum volume, the pressure increase continues exceeding the Carnot cycle parameters, causing more energy expended than captured in cooling, ending functionality. Therefore, the net work production ceases, rather than altered heat transfer, work to heat conversion, or phase skipping, each needing cycle phases maintained.
