JEE Main & Advanced AIEEE Solved Paper-2011

  • question_answer
    A thermally insulated vessel contains an ideal gas of molecular mass M and ratio of specific heats\[\gamma \]. It is moving with speed v and is suddenly brought to rest. Assuming no heat is lost to the surroundings, its temperature increases by   AIEEE  Solved  Paper-2011

    A) \[\frac{(\gamma -1)}{2R}M{{v}^{2}}K\]                    

    B) \[\frac{(\gamma -1)}{2(\gamma +1)R}M{{v}^{2}}K\]

    C) \[\frac{(\gamma -1)}{2\gamma R}M{{v}^{2}}K\]                  

    D) \[\frac{\gamma M{{v}^{2}}}{2R}K\]

    Correct Answer: A

    Solution :

                 \[\frac{1}{2}m{{v}^{2}}=\frac{n\times R\Delta T}{(\gamma -1)}\] \[\Rightarrow \,\,\,\Delta T=\frac{M{{V}^{2}}(\gamma -1)}{2R}\]
