← ScienceWhich outcome occurs when adiabatic expansion of supercooled water?
A)Spontaneous ice crystal nucleation begins✓
B)Density remains uniform throughout volume
C)Homogeneous boiling throughout the liquid
D)Vapor creation limited by heat input
💡 Explanation
Ice crystals will nucleate spontaneously due to adiabatic expansion lowering the temperature. This drop enhances local supersaturation. The mechanism is homogeneous nucleation, because interfaces are created spontaneously rather than heterogeneous seeds being present; therefore ice forms rather than uniform density or widespread boiling.
