Abstract

The wood-water system has been treated by the classical techniques of thermodynamics although the system is not perfectly reversible in the thermodynamic sense. This irreversibility is primarily because of sorption hysteresis, already noted in the discussion of the sorption isotherms for wood. Morton and Hearle (1962, 1975) pointed out that, because hysteresis indicates the existence of states of metastable equilibrium during moisture sorption, application of thermodynamic equations to such systems should be treated cautiously. Nevertheless, it is useful to consider moisture sorption as a reversible process in order to calculate the approximate magnitudes of certain thermodynamic properties.
