    If the compressibility of water is \[\sigma \](sigma) per unit atmospheric pressure, then the decrease in volume V due to p, atmospheric pressure will be

    A)  \[\sigma V/p\]

    B)         \[\sigma pV\]

    C)  \[\sigma /pV\]

    D)         \[\sigma p/V\]

    Correct Answer: B

    Solution :

    We have, compressibility \[=\frac{\Delta V/V}{p}\Rightarrow \sigma =\frac{\Delta V}{pV}\] or            \[\Delta V=\sigma pV\]
