Perfect Gas - Perfect Gas Nomenclature

Perfect Gas Nomenclature

The terms perfect gas and ideal gas are sometimes used interchangeably, depending on the particular field of physics and engineering. Sometimes, other distinctions are made, such as between thermally perfect gas and calorically perfect gas, or between imperfect, semi-perfect, perfect, and ideal gases. The assumptions are summarized in the following table.

Nomenclature 1
Nomenclature 2
Specific heat at constant V

Famous quotes containing the words perfect and/or gas:

    And then at last our bliss
    Full and perfect is,
    But now begins; for from this happy day
    The old Dragon underground,
    In straiter limits bound,
    Not half so far casts his usurped sway,
    And, wroth to see his kingdom fail,
    Swinges the scaly horror of his folded tail.
    John Milton (1608–1674)

    Man moves in all modes, by legs of horses, by wings of winds, by steam, by gas of balloon, by electricity, and stands on tiptoe threatening to hunt the eagle in his own element.
    Ralph Waldo Emerson (1803–1882)
