In physics in particular in statistical mechanics, the maxwell boltzmann distribution is a particular probability distribution named after james clerk maxwell and ludwig boltzmann it was first defined and used for describing particle speeds in idealized gases, where the particles move freely inside a stationary container without interacting with one another, except for very brief. Pdf on dec 1, 2006, jose manuel casado and others published maxwell, boltzmann, gibbs.

Beiser mentions them maxwell boltzmann, boseeinstein, fermidirac in this section, but i will save that for later, when we treat the distributions in separate sections, beginning with the next section. Here, s is the entropy of a system in thermal equilibrium, w a probability, and k boltzmann s constant. Distribucion maxwell boltzmann termodinamica fisica khan academy en espanol. From the boltzmann equation to the maxwell boltzmann distribution a formula to relate entropy to probability often it is a lot more useful to think about entropy in terms of the probability with which different states are occupied.
