 Moisture sorption isotherms in term of thermodynamic aspect, and tobacco-water system were examined for oriental tobaccos. Energetic approaches were used to describe the moisture sorption behavior of tobaccos. Cured tobacco with high moisture content possesses energetic properties different from tobacco of low moisture content of the same type of leaves. Monolayer and surface area of adsorption were evaluated at several temperatures. The vapor pressure iso therm found to be consist of two phases.
