Abstract

An approach is suggested for solving the problem on finite velocity of heat propagation from the viewpoint of the kinetic theory. Interrelation has been established between this problem and the finite time for the distribution function to approach equilibrium. An approximation for the collision term in the kinetic Boltzmann equation has been found capable of providing the finite time for the equilibrium to be developed in an insulated system. By solving the Boltzmann equation, the distribution function is calculated to a first approximation through the agency of which the power-heat-conduction law is found, whose heat conduction equation describes the finite propagation velocity of thermal disturbances.
