How to Supercool Water: A SciShow Experiment

The video explains the freezing and boiling points of water and introduces the concept of supercooling, where water remains liquid below its freezing point. It describes how molecular energy affects the state of matter and the process of nucleation, which is necessary for ice formation. The video provides a step-by-step guide to creating supercooled water and demonstrates how to trigger ice formation by creating a nucleation site.

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

• Supercooling

• Condensation

• Evaporation

• Sublimation

Which state of matter has molecules with the highest energy?

• Plasma

• Gas

• Liquid

• Solid

What is a nucleation site in the context of freezing water?

• A site where water molecules condense

• A location where water molecules dissolve

• A central point where ice formation begins

• A place where water molecules evaporate

What should be avoided to successfully supercool water?

• Keeping the water still

• Opening the freezer frequently

• Using a watch to time the process

• Using purified water

What happens when you shake a bottle of supercooled water?

• It remains liquid

• It evaporates

• It boils

• It instantly freezes
