Which outcome results when rapid cooling induces defects within a crystalline metal?

A)Increased electrical resistance occurs rapidly
B)Elevated thermal conductivity is observed
C)Decreased yield strength is measured
D)Expanded magnetic hysteresis is detected

💡 Explanation

Increased electrical resistance arises because rapid cooling introduces lattice imperfections, enabling electron scattering, known as phonon scattering. This impedes electron flow, therefore increasing resistance, rather than enhancing conduction or affecting tensile attributes under equilibrium conditions.
