What is Gibb's paradox? Derive Sackur-Tetrode equation of entropy for a classical, ideal gas.
Gibbs' paradox arises in statistical mechanics when considering the entropy of mixing two identical gases. According to classical thermodynamics, mixing two different gases increases the entropy of the system. However, if the gases are identical, the mixing should not lead to an increase in entropy since the particles are indistinguishable. This contradiction suggests a flaw in the classical treatment of entropy.
