← ScienceWhich outcome occurs when the conduction band minimum lowers?
A)Increased electrical conductivity results therefore✓
B)Reduced thermal expansion observed overall
C)Higher ferromagnetic saturation achieved normally
D)Crystal lattice periodicity is disrupted thus
💡 Explanation
Increased conductivity occurs because lowering the band minimum results in more electrons being thermally excited into the conduction band—the mechanism driving conduction. Therefore, the electrical conductivity goes up rather than any change to expansion or magnetism being possible.
