“…In Table 1 (Eqs. 2, 3 and 4) the constants Xo, Co and Ko are the parameters of the entropic character and ∆H, Ho, Hm and HL (kJ/kg) are the heats of sorption of water in Xe, in the monolayer, in the multilayer, and in pure water, respectively (Martín-Santos et al, 2012;Moreira et al, 2008;Polachini et al, 2016;Rosa et al, 2013;Villa-Vélez et al, 2015). In the Peleg model, K1, K2, n1 and n2 are constants and have the restrictions that n1<1 and n2 >1.…”
