Molar Volume Model
Molar volume can be used to establish a connection with some significant physical properties, for example, viscosity, electrical conductivity and surface tension. It is the reciprocal of density multiplied by molar mass.
Model Description
The model used to describe the molar volume at ambient pressures is:
A simple polynomial is used to model non-magnetic volumetric expansivity above 298 K:
The model described above is implemented in Thermo‑Calc software with two parameters, V0 and VA, and α is the linear thermal expansivity at 1 bar and 3α is the volumetric thermal expansivity.
