    Kinetics of collisionless gas: equalization of temperature, growth of the coarse-grained entropy and the Gibbs paradox


    2009, Vol. 5, No. 3, pp.  377-383

    Author(s): Kozlov V. V.

    The Poincaré model for dynamics of a collisionless gas in a rectangular parallelepiped with mirror walls is considered. The question on smoothing of the density and the temperature of this gas and conditions for the monotone growth of the coarse-grained entropy are discussed. All these effects provide a new insight of the classical paradox of mixing of gases.
