Abstract. Internal thermal energy in solids contributes to vibrations (phonons) energy; spin waves (magnons) energy if solid has magnetism and fermions energy across very complicated mechanisms. Debye functions, mathematically, was estimated because they are considered a main term which controls in all equations of those contributions.
Semi-empirical equation has been obtained to nd (n3,4,5) transition metals specific heat to calculate some important physical constants.
Numerical analyses gives an agreement with experimental results on nd
transition metals. Comparison between theoretical and experimental was
