Hysteresis is related to

A. Sorption curve

B. Desorption curve

C. Sorption-desorption curve

D. None of the above

Answer: Option C

Solution(By Examveda Team)

Hysteresis is the dependence of the state of a system on its history.
Hysteresis is related to the Sorption - desorption curve, which means the equilibrium moisture content is different in desorption and adsorption processes.
The hysteresis between the adsorption isotherm and desorption isotherm is thought to be caused by the gradual desorption mechanism (percolation theory) due to the different size pores being combined.
