    One mole of an ideal monatomic gas undergoes a process described by the equation \[P{{V}^{3}}\] constant. The heat capacity of the gas during this process is

    A)  \[\frac{3}{2}R\]                       

    B)  \[\frac{5}{2}R\]

    C)  \[2R\]                          

    D)  \[R\]

    Correct Answer: D

    Solution :

    \[P{{V}^{3}}\] constant polytrophic process with n=3 \[C={{C}_{V}}+\frac{R}{1-n}\] \[=\frac{R}{r-1}+\frac{R}{1-n}\] \[\frac{R}{\frac{5}{3}-1}+\frac{R}{1-3}=R\]
