    If the pressure and absolute temperature of 2 L of carbondioxide gas are doubled, the value of the gas would become

    A)  2 L  

    B)                                        4 L  

    C)  5 L                         

    D)         7 L

    Correct Answer: A

    Solution :

    \[\frac{\text{pV}}{\text{T}}\,\text{=}\,\text{constant}\] \[\therefore \]  \[\frac{{{p}_{1}}{{V}_{1}}}{{{T}_{1}}}=\frac{{{p}_{2}}{{V}_{2}}}{{{T}_{2}}}\] \[\frac{p\times 2}{T}=\frac{2p\times {{V}_{2}}}{2T}\]                 \[{{V}_{2}}=2L\]
