Compressibility under isothermal (constant temperature ) compression/decompression thermodynamic process:
c_T = \frac{1}{\rho} \left( \frac{\partial \rho}{\partial p} \right)_T = - \frac{1}{V_m} \left( \frac{\partial V_m}{\partial p} \right)_T |
Isothermal Compressibility is material property and inverse to Isothermal bulk modulus :
\beta_T = \frac{1}{K_T} |
