    \[300\text{ }ml\]of a gas at \[{{27}^{o}}C\]is cooled to \[-{{3}^{o}}C\]at constant pressure. The final volume is:    

    A)  \[350\,l\]                           

    B)  \[270\text{ }ml\]

    C)  \[540\text{ }ml\]                            

    D)  \[135\text{ }ml\]

    Correct Answer: B

    Solution :

                    From Charles law \[\frac{{{V}_{1}}}{{{T}_{1}}}=\frac{{{V}_{2}}}{{{T}_{2}}}\] \[\frac{300ml}{300K}=\frac{{{V}_{2}}}{270K}\] \[{{V}_{2}}=270ml\]
