Boltzmann's entropy formula is a fundamental equation in statistical mechanics that relates the entropy \\( S \\) of a system to the number of microstates \\( \\Omega \\) associated with that system. The formula is expressed as: \\\[ S = k \\ln \\Omega \\\] where: - \\( S \\) is the entropy of the system. - \\( k \\) is Boltzmann's constant (\\( k \\approx 1.
