Abstract :The abnormal behavior of the specific heat of Imidazolium Perchlorate insert ignore into journalissuearticles values(Im-ClO4); was analyzed in terms of the power-law formula insert ignore into journalissuearticles values(including critical exponent α and fitting parameter JA); derived from the Ising model around the lower phase transition temperature of TC = 247 K. Moreover, the temperature dependence of some thermodynamic functions such as entropy, enthalpy, and the Gibbs free energy were calculated using the values of α and
