The useful idea
- The useful idea
Melting, or fusion, is a physical process that results in the phase transition of a substance from a solid to a liquid.
- How it works
This occurs when the internal energy of the solid increases, typically by the application of heat or pressure, which increases the substance's temperature to the melting point.
- Why it matters
At the melting point, the ordering of ions or molecules in the solid breaks down to a less ordered state, and the solid melts to become a liquid.
Why this matters
Look for Melting the next time you notice this pattern in everyday life.
