Given the molar specific heat cv of a gas at constant volume, you can determine the number of degrees of freedom s that are energetically accessible. for example, at room temperature cis-2-butene, c4h8, has molar specific heat cv=70.6jmol⋅k. how many degrees of freedom of cis-2-butene are energetically accessible?

    The molar specific heat Cv = R s / 2

    70.6 J/mol. K = (8.314 J/mol. K) * s / 2

    So the number of degrees of freedom are:

    s = 16.98 = 17

    The correct answer is 17

    The explanation:

    To get how many degrees of freedom of Cis-2-butene we are going to use this formula of the molar specific heat:

    Cv = R. s / 2

    when Cv is the molar specific heat = 70.6 J/mol. K

    and R is the ideal gas constant = 8.314 J/mol. K

    and S is the degrees of freedom of cis-2-butene : it is the number of independent coordinates to specify the motion of a molecule.

    so by substitution:

    70.6 J/mol. K = [8.314 J/mol. K] * s / 2

    So, the number of degrees of freedom = s = 16.98 ≈ 17
