Question

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

• A. 0.4 cc
• B.
• C. 0.025 cc
• D. 0.004 cc

Answer 1

The correct option is A

0.4 cc

$C=\frac{1}{K}=\frac{\frac{△V}{V}}{△P}\Rightarrow △V=C\times △P\times V$
$=4\times {10}^{-5}\times 100\times 100=0.4cc$
