Which term describes the ability to change into a liquid or molten state when heated to its melting point?

Explanation:
The concept here is fusibility—the ability of a material to melt and become a liquid when heated to its melting point. Fusibility describes how readily a solid will melt, which is essential for processes like casting or soldering where a material must flow as a liquid. This is different from elasticity (returning to its original shape after deformation), hardness (resistance to indentation), and toughness (resistance to fracture under impact). So the term that fits the description of melting into a liquid at the melting point is fusibility.
