Question

A material has normal density $\rho$ and bulk modulus K. Find the increase in the density of the material when subjected to an external pressure P from all sides.

Answer 1

We know that Bulk Modulus is given by-

$B=\frac{P}{\Delta V/V}=\frac{P}{\Delta \rho /{\rho }^2}$

$⟹\Delta \rho =\frac{P{\rho }^2}{K}=$ Increase in density
