← ScienceWhich outcome results when rapid heating causes a solid's temperature to rise above the melting point without uniform liquid formation?
A)Superheating above the equilibrium melting temperature✓
B)Sublimation directly into gaseous phase
C)Recrystallization into thermodynamically stable phase
D)Lowering average kinetic energy of molecules
💡 Explanation
Superheating occurs because the fusion process requires nucleation sites; therefore, the temperature rises above the equilibrium melting point before the phase transition if nucleation is insufficient rather than immediate melting or sublimation.
