The upper estimation of energy accommodation coefficient is obtained. It is shown that this coefficient tends to zero asymptotically for high temperatures. It means that at high temperatures the efficiency of heat transfer between gas and condensed body is small when gas–surface collisions occur in free–molecular regime.
