Entropy, Distance and Similarity Measures under Interval-Valued Intuitionistic Fuzzy Environment

It has been observed that generally the changes in enthalpy and entropy occur simultaneously (Oliveira et al., 2013; Correa et al., 2015; Goneli et al., 2016a, b; Silva et al., 2016), which according to Leffler (1995) allows to verify greater molecular interaction or bonds between molecules due to the reduction in the freedom or to the binding of the molecules in the system.

For Leffler (1955), if [T.sub.B] > [T.sub.hm], the sorption process is controlled by enthalpy; otherwise ([T.sub.B] < [T.sub.hm]), the process is controlled by entropy. Therefore, the desorption and adsorption processes of 'Malagueta' pepper seeds are controlled by the enthalpy, following the same behavior of various agricultural products (Oliveira et al., 2013; Goneli et al., 2016a; Silva et al., 2016).
