Question

The pressure of a medium is changed from $1.01\times {10}^{5}Pa$ to $1.165\times {10}^{5}Pa$ and change in volume is $10\%$ keeping temperature constant. The bulk modulus of the medium is

• A. $204.8\times {10}^{5}Pa$
• B. $102.4\times {10}^{5}Pa$
• C. $51.2\times {10}^{5}Pa$
• D. $1.65\times {10}^{5}Pa$

Answer 1

The correct option is D $1.65\times {10}^{5}Pa$

$K=\frac{\Delta P}{\Delta V/V}=\frac{(1.165-1.01)\times {10}^5}{10/100}=\frac{0.165\times {10}^5}{1/10}=1.65\times {10}^{5}pa$
