key term - Melting

Definition

Melting is the phase transition from a solid to a liquid. It occurs when a substance absorbs sufficient heat to overcome its molecular forces.

5 Must Know Facts For Your Next Test

  1. The melting point is the specific temperature at which a solid becomes a liquid.
  2. During melting, the temperature of the substance remains constant until all the solid has turned into liquid.
  3. The energy required to change a solid at its melting point to a liquid is called the latent heat of fusion.
  4. Impurities in a substance typically lower its melting point, causing it to melt over a range of temperatures rather than at one specific point.
  5. Melting is an endothermic process, meaning it absorbs heat from its surroundings.
