PhysicsEasysingle choice

The bulk modulus of water is $2 \times 10^{9} {N m}^{- 2}$ . The change in pressure required to increase the density of water by $0.1 %$ is -

Options:

Answer:

Solution:

The density would increase by $0.1 %$ if the volume decrease by $0.1 %$ ,

$K = \frac{Δ P}{\frac{Δ V}{V}}$

$\Rightarrow Δ P = K \frac{Δ V}{V} = 2 \times 10^{9} \times \frac{0.1}{100} = 2 \times 10^{6} N m^{- 2}$
