Volumetric thermal expansion coefficient
The volumetric thermal expansion coefficient (sometimes simply thermal expansion coefficient) is a thermodynamic property of a fluid given by
β = - (1 / ρ)(∂ρ/∂T)ρ const
where
ρ density T Temperature
β measures the fractional decrease in fluid density as temperature increases at constant pressure.
