# Coefficient of compressibility

From AMS Glossary

## coefficient of compressibility

(

*Or*compressibility.) The relative decrease of the volume of a system with increasing pressure in an isothermal process.This coefficient is where

*V*is the volume,*p*the pressure, and*T*the temperature. The reciprocal of this quantity is the bulk modulus.*Compare*coefficient of thermal expansion, coefficient of tension.
