← ScienceWhich outcome occurs when nanoscale heat engines suffer irreversible processes?
A)Kinetic energy converts to waste heat✓
B)Carnot efficiency becomes thermodynamically possible
C)Increased quantum entanglement occurs reliably
D)Reduced internal energy increases output work
💡 Explanation
As nanoscale heat engines encounter irreversibilities, energy dissipates via frictional/viscous contributions. This happens via the mechanism of viscous dissipation because energy is converted into thermal motion rather than useful work; therefore, kinetic energy dissipates into waste heat, rather than increased efficiency.
