Briefly explain Dulong-Petit, Einstein, and Debye's models for heat capacity. Draw a graph reflecting typical behavior of heat capacity versus temperature for a pure metal and discuss in which region which model is operative. Constants: Mass of electron: mo=9.11x10-31 kg Charge of electron: e=1.6x10-19 C Boltzman's constant: ke=1.38X10-23 J/K, Planck's constant: h= 6.626x10-34 Js Pi: n=3.14 1eV=1.6x10-19J
