Here's a breakdown:
* Melting Point: The temperature at which a solid substance transforms into a liquid.
* Molten: Describes the liquid state of a substance that has been heated above its melting point.
Examples:
* Molten rock: Lava, magma
* Molten metal: Used in casting and manufacturing processes
* Molten salt: Used in some chemical reactions and energy storage applications
Key Features of Molten Substances:
* Fluid: Molten substances have the ability to flow and change shape easily.
* High temperature: Molten substances are at temperatures significantly higher than their solid state.
* Increased reactivity: Molten substances can be more reactive chemically than their solid forms.
Note: The term "molten" is often used in geology, metallurgy, and other fields where high temperatures are involved.
