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 rights is "mistaken". He says that the question between what one has a right to do and who if anybody enforces it are separate issues. If rights are only negative then it simply means no one has a duty to enforce them, although individuals have a right to use any non-forcible means to gain the cooperation of others in protecting those rights. Therefore, he says "the distinction between negative and positive is quite robust." Libertarians hold that positive rights, which would include a right to be protected, do not exist until they are created by contract. However, those who hold this
