Science

Which outcome occurs when excessive molecular vibration within a crystal lattice increases at high temperature?

A)Increased material electrical resistance
B)Enhanced material superconductivity
C)Increased ferromagnetic alignment
D)Decreased coefficient of thermal expansion

💡 Explanation

Electron transfer is hindered because increased atomic motion through electron scattering lowers the mean free path; therefore, electrical resistance increases rather than superconductivity, because the mechanism of electron pairing is absent.
