A statistical definition of entropy, given by S = k ln W, where S and k are the entropy and Boltzmann's constant, respectively, and W is the probability of finding the system in a particular state.

In physics, specifically non-equilibrium statistical mechanics, the Boltzmann equation or Boltzmann transport equation (BTE) describes the statistical behaviour of a thermodynamic system not in thermodynamic equilibrium. It was devised by Ludwig Boltzmann in 1872. The classic example is a fluid with temperature gradients in space causing heat to f...

An important equation in statistical mechanics that connects entropy (S) with molecular disorder (W). It can be written: S = k log W where k is Boltzmann's constant. The Austrian physicist Ludwig Boltzmann first linked entropy and probability in 1877. However, the equation as shown, involving ...
