In statistical mechanics, Boltzmann's equation is a probability equation relating the entropy S , also written as S B , of an ideal gas to the multiplicity, the number of real microstates corresponding to the gas's macrostate: where k B is the Boltzmann constant and equal to 1.380649 × 10−23 J/K, and ln is the natural logarithm function. In short, the Boltzmann formula shows the relationship between entropy and the number of ways the atoms or molecules of a certain kind of thermodynamic system can be arranged.
