← ScienceWhich outcome arises when substantial interstitial impurities distort a crystal lattice?
A)Increased electrical resistance occurs✓
B)Enhanced thermal conductivity results
C)Improved tensile strength develops
D)Reduced optical transparency happens
💡 Explanation
Increased electrical resistance occurs because lattice distortion interrupts electron flow via phonon scattering, rather than promoting smooth passage. Phonon scattering is the operative mechanism; therefore, resistance increases because electron mobility suffers, rather than the other outcomes.
