    During an adiabatic process, the pressure of a gas is found to be proportional to the cube of its temperature. The ratio of \[\frac{{{C}_{p}}}{{{C}_{\upsilon }}}\] for the gas is 

    A) \[\frac{4}{3}\]

    B)  2

    C) \[\frac{5}{3}\]

    D) \[\frac{3}{2}\]

    Correct Answer: D

    Solution :

    According to question \[p\propto {{T}^{3}}\] \[pV=nRT\] And \[p\propto {{T}^{3}}\] \[\Rightarrow \] \[{{p}^{2}}{{V}^{3}}=\]constant \[p{{V}^{3/2}}=\]constant \[\because \] \[p{{V}^{\gamma }}=\]constant \[\therefore \] \[\gamma =\frac{3}{2}\]
