Understanding Instantaneous Freezing and Supercooling

What is required for water to freeze besides just dropping below zero degrees Celsius?

• An increase in humidity

• Molecules forming a specific structure

• The presence of light

• A decrease in air pressure

How do water molecules need to behave to form ice?

• They need to expand

• They need to come closer and align

• They need to evaporate

• They need to move faster

What role do impurities play in the freezing of water?

• They have no effect

• They increase the freezing point

• They help water molecules align

• They prevent freezing

What is the phenomenon called when pure water remains liquid below its freezing point?

• Supercooling

• Ultracooling

• Hypercooling

• Subcooling

What action can trigger the instant freezing of supercooled water?

• Heating the water

• Shaking the bottle

• Slamming the bottle on a surface

• Adding more water
