8. The adsorption and desorption isotherms for a biomaterial are given in the figure below (for a temperature of 25.0C ). The biomaterial had an initial moisture content of 20.0% ( % dry basis) but was then transferred for storage to a room at 40.0%RH at 25.0C. a. Label the adsorption curve and the desorption curve. What would be the final equilibrium moisture content (in \% db) of the biomaterial after storage for several weeks in the new conditions? b. Did the biomaterial gain or lose moisture over time to adjust to the new storage conditions? c. If the total mass of the biomaterial was 1,000kg initially, what would be the final mass after equilibrating to the new storage conditions (40.0%RH at 25.0C)
