Gibbs paradox


 

In a simple derivation based on the ideal gas law, the entropy S is not an extensive variable as it must be, leading to an apparent paradox known as the Gibbs paradox. The difficulty is resolved by letting the particles be indistinguishable. The resulting equation for the entropy of an ideal Maxwell-Boltzmann gas is known as the Sackur-Tetrode equation.
