What is melting?

  • (noun): The process whereby heat changes something from a solid to a liquid.
    Synonyms: thaw, melt, thawing

Melting, or fusion, is a physical process that results in the phase transition of a substance from a solid to a liquid. The internal energy of a substance is increased, typically by the application of heat or pressure, resulting in a rise of its temperature to the melting point, at which the ordering of ionic or molecular entities in the solid breaks down to a less ordered state and the solid liquefies. An object that has melted completely is molten. Substances in the molten state generally have reduced viscosity with elevated temperature; an exception to this maxim is the element sulfur, whose viscosity increases to a point due to polymerization and then decreases with higher temperatures in its molten state.

Famous quotes containing the word melting:

    Slow, slow, fresh fount, keep time with my salt tears;
    Yet slower yet, oh faintly gentle springs:
    List to the heavy part the music bears,
    “Woe weeps out her division when she sings.”
    Droop herbs and flowers;
    Fall grief in showers;
    “Our beauties are not ours”:
    Oh, I could still,
    Like melting snow upon some craggy hill,
    Drop, drop, drop, drop,
    Since nature’s pride is, now, a withered daffodil.
    Ben Jonson (1572–1637)

    Fearful of sentimentality, I disown my tears and melting heart.
    Mason Cooley (b. 1927)

    O ruddier than the cherry,
    O sweeter than the berry,
    O Nymph more bright
    Than moonshine night,
    Like kidlings blithe and merry.
    Ripe as the melting cluster,
    No lily has such lustre,
    Yet hard to tame,
    As raging flame,
    And fierce as storms that bluster.
    John Gay (1685–1732)
