Bulk modulusCompressibility depends on the thermodynamic conditions at which it is measured and as such is not a material property.
The two major medium compression/decompression processes are isothermal and isentropic which result in different values of compressibilityBulk modulus:
Both and are not dependent on the amount of chemical substance and defined under a clear conditions of thermodynamic process and as such are the material properties and properly tabulated for the vast majority of materials.
In engineering practise, when the term CompressibilityBulk modulus is used as material property it normally means Isothermal Compressibility: .Compressibility is related to Z-factor
and Formation Volume Factor (FVF) as:...
