Molten

The transcript explains the concept of molten substances, which are materials that remain solid at high temperatures but can be melted by heating. It highlights the application of this concept to materials like glass, rock, and metals. Additionally, it discusses the process of electrolysis, which requires ionic compounds to be in a molten state to allow ions to move freely.

What does the term 'extreme heat' imply in the context of materials?

Which substances are typically associated with extreme heat?

Why do ionic compounds need to be in molten form for electrolysis?

What happens to the ions in ionic compounds when they are heated to a molten state?

How does the state of a substance affect its ability to conduct electricity during electrolysis?
