. a) If the classical theory of specific heat were valid, what would be the thermalenergy of one mole of Cu at the temperature T=0D? The Debye temperaturefor Cu is 340°K.b) Calculate the actual thermal energy according to the Debye theory (use Fig.3.13), and compare with the classical value obtained above. (For the purpose ofthis calculation, you may approximate the Debye curve by a straight line joiningthe origin to the point on the Debye curve at T=0p.)c) What is the order of magnitude of the maximum displacement of a Cu atom atthe Debye temperature? Compare this displacement with the interatomic distance.C., cal/g-mol - "KCu, 343°KAg. 226°K■ Pb, 102°Kx C, 1860°K0.5T/ODFig. 3.13 Specific heats versus reduced temperature for four substances.
