H2 hysteresis
Webshould observe a hysteresis loop with condensation and evapora-tion branches characteristic of the distributions of the pore size and of the neck size, respectively. The global hysteresis loop should be the sum of the individual hysteresis loops. In such a system there is a priori no reason to observe a hysteresis loop of type H2.
