Volume expansion is defined as the increase in the volume of the solid on heating. The volumetric thermal expansion coefficient is the most basic thermal expansion coefficient and the most relevant for fluids. Coefficient of Thermal Expansion CTE 10-6 C-1.
They are similar except the length variable would be exchanged for volume and the linear.
Aluminum 99996 20-100C 68-212F. Volume expansion is defined as the increase in the volume of the solid on heating. The volumetric thermal expansion coefficient is the most basic thermal expansion coefficient. The volumetric coefficient of expansion determines how the volume of a solid object will expand or contract as a function of pressure.
