Physical adsorption of vapor on ice

摘要: Abstract Physical adsorption studies of simple nonpolar hydrocarbon vapors on ice are described. The isotherms obtained cover a temperature range from −96°C to −30°C, or up roughly the where drastic sintering occurs. Results compared existing data for liquid water. At temperatures below that about −35°C, behavior is characterized by low energies, with isosteric heats lower than heat condensation at coverages and rising as coverage increases multilayer formation. As increased −35°C above, dramatically changes similar water, marked abnormally high which drop increases. explanation proposed H 2 O molecules in surface actively involved process higher temperatures, manner case
