    A certain mass of gas occupies a volume of 2 litre at STP keeping the pressure constant. At what temperature would the gas occupy a volume of 4 litre?

    A)  \[{{50}^{o}}C\]                                

    B)  \[{{100}^{o}}C\]

    C)  \[{{273}^{o}}C\]                              

    D)  \[{{546}^{o}}C\]

    Correct Answer: C

    Solution :

                    Acc. to Charles law, \[V\propto t\] \[\frac{{{V}_{1}}}{{{T}_{1}}}=\frac{{{V}_{2}}}{{{T}_{2}}}\] \[\frac{2}{273}=\frac{4}{{{T}_{2}}}\] \[{{T}_{2}}=\frac{4\times 273}{2}\] \[{{T}_{2}}=546K\]                 or            \[{{T}_{2}}=546-273\]                                 \[{{T}_{2}}={{273}^{o}}C\]
