  • question_answer
    Equal volumes of two monoatomic gases, A and B, at same temperature and pressure are mixed. The ratio of specific heats\[(cp/cv)\] of the mixture will be                                  

    A)  0.83      

    B)  1.50      

    C)  3.3        

    D)  1.67

    Correct Answer: D

    Solution :

    For monoatomic gases,                 \[\frac{{{c}_{p}}}{{{c}_{v}}}=\gamma =\frac{\frac{5}{2}R}{\frac{3}{2}R}1.67\]                 \[\because \] Equal volumes of two monoatomic gases are mixed.                 \[\therefore \] \[\gamma \] will remain the same.
