    In gases of diatomic molecules, the ratio of two specific heats of gases\[\frac{{{C}_{P}}}{{{C}_{\upsilon }}}\]will be:

    A)  1.2               

    B)  1.33

    C)  1.66              

    D)  1.4

    Correct Answer: D

    Solution :

     It is known that specific heat of diatomic gases at constant pressure \[{{C}_{P}}=\frac{7}{2}R\] and specific heat at constant volume \[{{C}_{\upsilon }}=\frac{5}{2}R\] Hence, \[\frac{{{C}_{P}}}{{{C}_{\upsilon }}}=\frac{\frac{7}{2}R}{\frac{5}{2}R}=\frac{7}{5}=1.4\]
