Ideal gas except for the specification of these constants. The results of the quantum Boltzmann gas are used in a number of cases including the Sackur–Tetrode equation for the entropy of an ideal gas and the Saha ionization equation for a weakly ionized plasma. The classical thermodynamic properties of an ideal gas can be described by two equations of state: The ideal gas law is the equation of state for an ideal gas, given by: where The ideal gas law is an extension of experimentally discovered gas laws. It can also be derived from microscopic considerations. Real fluids at low density and
Positive Songs for Negative People eclectic musicianship combined with uplifting and introspective lyrics, calling it "an invigorating, infectious set that reaffirms Turner's faith in music's power to motivate and heal." Alexis Petridis of "The Guardian" found some of the material weary with its earnestness and rousing bombast, but said that they were outweighed with more melancholic tracks like "Silent Key" and "Song for Josh", concluding that, "For all its flaws, "Positive Songs for Negative People" feels like the work of someone who knows exactly what he’s doing."
