MCQ
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 ......... $cc$
  • $0.4 $
  • B
    $4 \times {10^{ - 5}}$
  • C
    $0.025$
  • D
    $0.004$

Answer

Correct option: A.
$0.4 $
a
(a) $C = \frac{1}{K} = \frac{{\Delta V/V}}{{\Delta P}}$$\Rightarrow $ $\Delta V = C \times \Delta P \times V$

$ = 4 \times {10^{ - 5}} \times 100 \times 100 = 0.4cc$
