Volumetric and linear expansion coefficients in isotropic materials

Coefficients of thermal expansion describe how the size of an object changes with a change in temperature at a constant pressure. In isotropic materials, the volumetric coefficient is three times the linear one.

Conditions:

  1. The material is isotropic.

  2. The pressure is constant during the volume change.
