Determination of the Binding Heat of Water in Tobacco - Bestimmung der Bindungswärme des Wassers im Tabak

The evolution of the desorption curves of a Greek cigarette brand at temperatures of 15° to 30°C is presented by means of the formula established by Brunauer, Emmet and Teller, and used to determine the heat of binding of water at 40 % to 70 % relative humidity of air. The mechanical linkage force of water is shown to be confirmed by the calculated heat values.
