The Exchange of Energy Between Organic Molecules and Solid Surfaces Part II. Accommodation Coefficients and Specific Heats of Paraffin Hydrocarbons and the Influence of Temperature on the Accommodation Coefficients (Including Argon) at Some 10—6 mm (Hg) Pressure

Abstract

The investigation of the accommodation coefficients of the paraffin hydrocarbons and their relation to the specific heats reported in Part I of this series has been extended to various temperatures of the nickel surface and to various gas temperatures. The results are, within the experimental error of about 1 percent, in full agreement with the general formulae derived in Part I, by which the accommodation coefficients of the paraffins were related to their molecular weights and their specific heats. A complete summary of these relations is given at the end of this paper.
