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
Experiments and Observations on Electricity the Leyden jar had an accumulation of electrical fire, which he labeled as "positive" ("plus"), and the other side had a deficiency of electrical fire, labeled "negative" ("minus"). These losses and gains of electrification were exactly equal and are essentially the modern law of charge conservation except that it is now recognized that negative charges exist in their own right, not just as a deficiency of positive charges. It is an important principle in modern science that explains the microphysics of the electrification of gross bodies. In these letters, Franklin introduced technical words that we use today for things related
