Which term would you use to describe the ability to change into a liquid or molten state when heated to its melting point?

Explanation:
Fusibility is the term for a material’s tendency to melt into a liquid when heated to its melting point. This describes how readily a solid can be melted, which is important for processes like casting, welding, or soldering where a liquid phase is needed. Elasticity refers to returning to shape after deformation, plasticity to permanent shape change, and toughness to resisting fracture; none describe melting behavior, so fusibility best fits the idea of turning into a liquid at the melting point.
