Summary

Isosters for Western white pine were experimentally determined at temperatures of 30, 45, 60 and 70°C and relative humidities between 10 and 90%, approximately. The enthalpyentropy and free energy changes for water, were calculated and analyzed. The enthalpy-entropy compensation was proven to exist and the isokinetic temperature was calculated.
