Vedclass · Answer

(A) The bulk modulus $(B)$ is defined as the ratio of volumetric stress to volumetric strain,given by $B = -\Delta P / (\Delta V / V)$.For a given change in pressure $(\Delta P)$,gases undergo a much larger change in volume $(\Delta V)$ compared to solids and liquids because gas molecules are loosely packed.Since $B$ is inversely proportional to the fractional change in volume $(\Delta V / V)$,a large $\Delta V$ results in a very small value of $B$.Therefore,gases have the minimum volume elasticity compared to solids and liquids.
