A general model for supercooled liquid is proposed which involves the "Ideal Supercooled Liquid, " crystal nucleus, microcrystallite and crystal. In this model, in homogeneity which appears in supercooled liquid is attributed to these nuclei and microcrystallites. The authors consider that in amorphous state, heat energy is absorbed in two ways, one by the kinetic portion and the other by the configurational portion. While the former absorbs heat energy instantaneously, the latter absorbs through the molecular relaxating process. From this simple model, the authors derive a formula for the specific heat of amorphous substance, which shows that (1) supercooled liquid to glassy transition is superficial one depending on the heating rate in the measurement, and (2) if perfect equilibrium is maintained at all temperatures in measuring process, we get perfect continuous C_p〜T curve. In addition, the method to determine the true equilibrium value by the use of Nernst's method is proposed. Some characteristics of specific heat curve are discussed with success.
