  • question_answer In order to increase the temperature of the gas filled in a closed vassel by \[{{0.5}^{o}}C\]its pressure is increased by 2%. The initial temperature of the gas is :-

    A)  \[400\text{ }K~\]

    B)  \[250\text{ }K\]

    C)  \[25\text{ }K\]             

    D)  \[-248\text{ }K\]

    Correct Answer: C

    Solution :

    Closed vessel V= const.      \[\therefore \]   \[P\propto T\] so \[T=\frac{\Delta T}{(\Delta P/P)%\,}K\] \[T=\frac{0.5}{2}\times 100\,K=25\,K\]
