← ScienceWhich inefficiency arises when an irreversible refrigeration cycle cools materials?
A)Increased entropy, system energy loss✓
B)Decreased enthalpy, constant system volume
C)Reduced heat-transfer, constant pressure
D)Eliminated exergy, isentropic expansions
💡 Explanation
Entropy increases due to irreversibilities, and this happens via increased heat transfer as the refrigeration cycle operates. Therefore, an increase in entropy leads to energy losses in the system, because system energy can only be converted if it retains useful organized work rather than disorganized energy.
