The bulk modulus (K) of a fluid, gas or solid denotes the resistance to change of the material when a uniform pressure is applied. It is given by the ratio of volume stress to volume strain:

with P being pressure and V being volume. The delta (Δ) represents change.

In terms of VP and VS

We can express the modulus in terms of acoustic velocity:[1]
