    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)  \[50{}^\circ C\]          

    B)  \[100{}^\circ C\]

    C)  \[273{}^\circ C\]         

    D)  \[546{}^\circ C\]

    Correct Answer: C

    Solution :

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