Which behavior causes reduced conductivity from increased lattice temperature?

A)Decreased electron mean free path
B)Increased number of electron collisions
C)Expanded interatomic spacing
D)Narrowing of material's band gap

💡 Explanation

Increased temperature causes increased lattice vibrations, a mechanism called electron-phonon scattering, which decreases electron mean free path and raises resistance. Therefore, conductivity decreases rather than interatomic modifications or band gaps changing, because electron flow is impeded.
