    During an adiabatic process of an ideal gas, if P is proportional to \[\frac{1}{{{V}^{1.5}}}\], then the ratio of specific heat capacities at constant pressure to that at constant volume for the gas is

    A) 1.5

    B) 0.25  

    C) 0.75

    D) 0.4

    Correct Answer: A

    Solution :

    [a] As \[\] \[\therefore \gamma \text{=1}\text{.5}\left( \therefore \text{Process is adiabatic} \right)\] As we know, \[\frac{{{C}_{P}}}{{{C}_{V}}}=\gamma \text{                }\therefore \frac{{{C}_{P}}}{{{C}_{V}}}=5\text{       }\]
