The Peng-Robinson equation is often used for hydrocarbons and nonpolar substances.
This is a generic term. The Lattimer-Swesty one, derived from the liquid drop model, is often used for nuclear matter in astrophysical simulations. For gravitating substances, one can be parametrized in terms of w, which is zero for normal matter, one-third for radiation, and minus one for a cosmological constant. The Peng-Robinson equation is often used for hydrocarbons and nonpolar substances. The virial equation is a rigorous result for gases, but the infinite series fails at high density. For ten points, name this type of physical relation, of which the most famous examples are the van der Waals and ideal gas equations.
