Flame

A flame (from Latin flamma) is the visible, gaseous part of a fire. It is caused by a highly exothermic reaction taking place in a thin zone. Some flames, such as the flame of a burning candle, are hot enough to have ionized gaseous components and can be considered plasma. There is, however, disagreement on this subject.

Famous quotes containing the word flame:

    The great war that broke so suddenly upon the world two years ago, and which has swept up within its flame so great a part of the civilized world, has affected us very profoundly.... With its causes and its objects we are not concerned. The obscure fountains from which its stupendous flood has burst we are not interested to search for or explore.
    Woodrow Wilson (1856–1924)

    It might become a wheel spoked red and white
    In alternate stripes converging at a point
    Of flame on the line, with a second wheel below,
    Just rising, accompanying, arranged to cross,
    Through weltering illuminations, humps
    Of billows, downward, toward the drift-fire shore.
    Wallace Stevens (1879–1955)

    The poppy that my heart was,
    formed to bind all mortals,
    made to strike and gather hearts
    like flame upon an altar,
    fades and shrinks, a red leaf
    drenched and torn in the cold rain.
    Hilda Doolittle (1886–1961)
