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 with negative rights of physicians. In controversial areas such as abortion and assisted suicide, medical professionals may not wish to offer certain services for moral or philosophical reasons. If enough practitioners opt out as a result of conscience, a right granted by conscience clause statutes in many jurisdictions, patients may not have any means of having their own positive rights fulfilled. Such was the case of Janet Murdock, a Montana woman who could not find any physician to assist her suicide in 2009. This controversy over positive and negative rights in medicine has become a focal point in the ongoing
