← ScienceWhich effect occurs when an amorphous solid devitrifies?
A)Grains grow via Ostwald ripening✓
B)Superconductivity onset increases rapidly
C)Viscosity approaches zero asymptotically
D)Ferromagnetic domains spontaneously disappear
💡 Explanation
Devitrification causes crystal nucleation and growth; Ostwald ripening causes larger crystal domains to grow therefore, grain size noticeably increases rather than other phase transitions appearing or viscosity dropping radically, different processes, different conditions.
