    The compressibility of water is \[4\times {{10}^{-5}}\] per unit atmospheric pressure. The decrease in volume of 100 cubic centimeter of water under a pressure of 100 atmosphere will be                                                           [MP PMT 1990]

    A)                                 0.4 cc                     

    B)                                 \[4\times {{10}^{-5}}\,cc\]                

    C)                                 0.025 cc                

    D)                                             0.004 cc

    Correct Answer: A

    Solution :

                        \[C=\frac{1}{K}=\frac{\Delta V/V}{\Delta P}\]Þ \[\Delta V=C\times \Delta P\times V\]             \[=4\times {{10}^{-5}}\times 100\times 100=0.4cc\]
