This equation of state (EOS) corresponds to identical non relativistic particles of rest mass is
The (non-relativistic) chemical potential is then
The pressure is given by the (zero-temperature) First Law of Thermodynamics:
The (non-relativistic) specific enthalpy is :
According to the (zero-temperature) First Law of Thermodynamics, the specific enthalpy is related to the chemical potential by
From this expression and relation (2), the expression of the particle density in term of the specific enthalpy is
The energy density and pressure as functions of H can then be obtained by inserting this relation into Eq. (1) and (3).
