Isobaric expansion coefficient beta

## Information

This function returns the isobaric expansion coefficient at constant pressure, which is zero for this medium. The isobaric expansion coefficient at constant pressure is

βp = - 1 ⁄ v (∂ v ⁄ ∂ T)p = 0,

where v is the specific volume, T is the temperature and p is the pressure.
