Modisette, Jerry L.2014-03-142014-03-141960-01-05etd-06102012-040033http://hdl.handle.net/10919/43020The following results have been obtained from this derivation of the velocity and directional distributions of subliming molecules: (1) Equations for tart velocity distributions normal and parallel to the surface as functions of temperature, and for the normal distribution, function of the potential barrier to sublimation. (2) Using the velocity distributions, equations for the directional distributions. (5) The average velocity normal to the surface is different from the average velocity of gas molecules normal to the surface at the same temperature.27 leavesBTDapplication/pdfenIn CopyrightLD5655.V855 1960.M635Molecular dynamicsThesishttp://scholar.lib.vt.edu/theses/available/etd-06102012-040033/
