The Peng-Robinson equation accounts for the acentric factor or non-sphericity of these substances that have a compressibility factor of one.
The Peng-Robinson equation accounts for the acentric factor or non-sphericity of these substances that have a compressibility factor of one. One model predicts that they have negative entropy as temperature approaches zero; that is the Sackur-Tetrode equation for monatomic ones. Taking into account particle size and intermolecular forces for an equation that describes these substances gives the more accurate Van der Waals equation. Helium behaves most like these substances at high temperature and low pressure. They are described by a combination of Charles', Gay-Lussac's, and Boyle's Laws. For 10 points, name these substances whose namesake law states that P V equals n R T.
