Which term refers to the ability to change into a liquid when heated to its melting point?

• A. Recycle
• B. Reuse
• C. Fusibility
• D. Reduce

Answer: (C)

Fusibility is the property that describes how readily a solid turns into a liquid when heated to its melting point. When heat is applied, a solid gains energy until it reaches its melting point, at which point its rigid structure breaks down enough for the material to flow as a liquid. Materials with high fusibility melt easily at lower temperatures, which is important in processes like soldering and casting because you want the material to melt and flow to fill gaps. The other terms relate to environmental waste practices (recycling, reusing, reducing) and don’t describe how a material behaves when heated.
