Speed of sound

    how does the speed of sound vary with temperature in an ideal gas? how do we derive this relation?

    Isn't the speed of sound directly proportionate to the medium's density?

    The speed of sound is proportional to the square root of the absolute temperature:

    [tex]c = \sqrt{k R T}[/tex]

    c = speed of sound
    k = ratio of specific heats (1.4 for air)
    R = Ideal gas constant
    T = Temperature
