Gas Constant - Relationship With The Boltzmann Constant

Relationship With The Boltzmann Constant

The Boltzmann constant kB (often abbreviated k) may be used in place of the gas constant by working in pure particle count, N, rather than amount of substance, n, since

where NA is the Avogadro constant. For example, the ideal gas law in terms of Boltzmann's constant is

where N is the number of particles (atoms or molecules).

Famous quotes containing the words relationship and/or constant:

    “Film music should have the same relationship to the film drama that somebody’s piano playing in my living room has to the book I am reading.”
    —Igor Stravinsky (1882–1971)

    “There exists a black kingdom which the eyes of man avoid because its landscape fails signally to flatter them. This darkness, which he imagines he can dispense with in describing the light, is error with its unknown characteristics.... Error is certainty’s constant companion. Error is the corollary of evidence. And anything said about truth may equally well be said about error: the delusion will be no greater.”
    —Louis Aragon (1897–1982)
