Moisture content entropy change

In measurements of the dielectric relaxation of water adsorbed on acetylated wood, a large change in the activation enthalpy and entropy of dielectric relaxation was found to occur at 6 % moisture content (Zhao etal., 1994), this presumably being attributable to the onset of formation of capillary water in the cell wall. [Pg.71]

Free Energy and Entropy Changes. The heat of sorption Qi consists of two parts, the free energy change AG and the entropy change AS. The loss in free energy AG (cal/g of water) can be calculated at any moisture content by... [Pg.157]

In many cases, b will be nonzero, and a function of moisture content. The difference between the free energy change and the enthalpy associated with adsorbed moisture has been associated with the entropy changes accompanying the dimensional changes as fibers swell on the uptake of moisture [21]. [Pg.741]
