At what temperature can supercooled water droplets exist?

• A. Above 0°C
• B. Between 0°C and -10°C
• C. Down to -45°C
• D. Below -45°C

Answer: (C)

Supercooled water droplets can exist in a state where they remain liquid even at temperatures well below freezing, typically down to about -40°C to -45°C. This occurs because supercooled water has not yet formed ice crystals, a process that requires nucleation to initiate. When the temperature drops, water molecules still retain sufficient energy to remain in the liquid state despite being below the freezing point. This phenomenon is closely related to how liquid water behaves when conditions are right and can stay in a liquid phase without transitioning to solid ice. Once supercooled, if any impurity or disturbance occurs, the droplets can rapidly freeze. The other temperature ranges mentioned do not accurately represent the capabilities of supercooled water; thus, those options do not align with the established science of supercooling.
