After a century, the kinetic theory of gases was also won the rapid development of .1857, the Clausius for the first time clearly statistical concepts, derived gas pressure, volume and temperature inter-correct relations, but also in 1858 introduced the concept of .1859 free path of molecular motion, the Maxwell velocity distribution law is derived, established the mathematical theory of transport processes .1868, the Boltzmann velocity distribution law was introduced in the gravitational field .
