  • question_answer
    The adiabatic elasticity of hydrogen gas \[(\gamma =1.4)\] at NTP is

    A) \[1\times {{10}^{5}}\ N/{{m}^{2}}\]  

    B) \[1\times {{10}^{-8}}\ N/m2\]

    C) \[1.4\ N/{{m}^{2}}\]

    D) \[1.4\times {{10}^{5}}N/{{m}^{2}}\]

    Correct Answer: D

    Solution :

    [d]\[{{E}_{\varphi }}=\gamma P=1.4\times (1\times {{10}^{5}})=1.4\times {{10}^{5}}N/{{m}^{2}}\]
