Elastic Modulie

Question

The compressibility of water is $4 \times 10^{- 5}$ per unit atmospheric pressure. The decrease in volume of 100 cm³ of water, under a pressure of 100 atmosphere, will be

Moderate

A

0.4 cm³
B

$4 \times 10^{- 5} {cm}^{3}$
C

$0.025 {cm}^{3}$
D

$0.004 {cm}^{3}$

Solution

$K = 4 \times 10^{- 5} per unit atm$
OP = 100 atm
$B = \frac{1}{K} = - OP / \frac{ΔV}{V}$
$\Rightarrow ΔV = ΔP \times x \times V$
$ΔV = 100 \times 4 \times 10^{- 5} \times 100 = 0.4 c m^{3}$
