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 by the Czech jurist Karel Vasak, may include other civil and political rights such as police protection of person and property and the right to counsel, as well as economic, social and cultural rights such as food, housing, public education, employment, national security, military, health care, social security, internet access, and a minimum standard of living. In the "three generations" account of human rights, negative rights are often associated with the first generation of rights, while positive rights are associated with the second and third generations. Some philosophers (see criticisms) disagree that the negative-positive rights distinction is useful or valid.
