The exact relationship between compressibility (β) and Bulk Modulus (k) is which one among the following? a) β = 1/k b) β = k c) β = 3k d) β = k/4

β = 1/k is the correct relation because the compressibility β of a liquid is defined as the ratio of volumetric strain to the compressive stress while Bulk Modulus is the ratio of compressive stress to volumetric strain.
