    A perfect gas at \[{{27}^{o}}C\] is heated at constant pressure to\[{{327}^{o}}C\]. If original volume of gas at \[{{27}^{o}}C\] is V, then volume at \[{{327}^{o}}C\] is

    A)  V                                

    B)  3V

    C)  2V                              

    D)  VII

    Correct Answer: C

    Solution :

     From Charles law \[V\propto T\] \[\therefore \]        \[\frac{{{V}_{2}}}{{{V}_{1}}}=\frac{{{T}_{2}}}{{{T}_{1}}}=\frac{327+273}{27+273}=\frac{600}{300}=2\] \[\Rightarrow \]\[{{V}_{2}}=2V\]
