    At what pressure a quantity of gas will occupy a volume of \[60\,ml\], if it occupies a volume of \[100ml\] at a pressure of \[720mm\]? (while temperature is constant) :    [Pb. CET 2000]

    A)                 \[700\,mm\]     

    B)                 \[800\,mm\]

    C)                 \[100\,mm\]     

    D)                 \[1200\,mm\]

    Correct Answer: D

    Solution :

               According to Boyle's law                    \[{{P}_{1}}{{V}_{1}}={{P}_{2}}{{V}_{2}}\] Þ \[{{P}_{1}}\times 60=720\times 100\]                                 \[{{P}_{1}}=\frac{720\times 100}{60}=1200mm\]
