← ScienceWhich outcome is observed when adiabatic expansion causes quenching?
A)Homogeneous nucleation throughout the volume✓
B)Grain boundary sliding increases rapidly
C)Eutectic transformation initiates immediately
D)Rapid disaccharide degradation accelerates decay
💡 Explanation
Adiabatic expansion during quenching decreases the temperature and increases supersaturation, leading to homogeneous nucleation because the system attempts to minimize the overall free energy by forming nuclei throughout, therefore nuclei form more broadly, rather than localized at the surfaces.
