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
Negative and positive atheism no God. He categorizes himself as a "de facto atheist" but "not" a "strong atheist" on this scale. Within negative atheism, philosopher Anthony Kenny further distinguishes between agnostics, who find the claim "God exists" uncertain, and theological noncognitivists, who consider all talk of gods to be meaningless. Jacques Maritain used the negative/positive phrases as early as 1949, but with a different meaning and in the context of a strictly Catholic apologist. Goparaju Ramachandra Rao (1902–1975), better known by his nickname Gora, was an Indian social reformer, anti-caste activist, and atheist. He proposed a philosophy he called "positive atheism", which treated
