. 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.

3.2. The simulation of parameter-distributed processes is connected with discretization in space and time. The distribution of changes in the temperature x of a heated at the front massive long metal piece is described by the following partial differential equation: Əx(z,t) F x(z,t) a[x(z,t) - 0,]+b- Əz? where 0, is the ambient temperature, a and b are constants. Derive the discrete model by applying discretization first with respect to z (z; = i.Az) and after that with respect to t (tx = k.At), using backward finite differences for the corresponding derivatives.
