Methyl cellulose (MC) hydrogels are thermoreversible physical hydrogels and their gelation is an endothermic process. A model consisting of a generalized expression for two bell-shape curves was formulated to describe and capture enthalpy changes that take place during the gelation of an aqueous sol...
