b) The classical Dulong - Petit Law states that Cv = 3R where R is the ideal gas C constant and Cv is the heat capacity at constant volume. However, experimentally C, is found to vary with temperature as shown in Figure 1 at low temperatures C₂ 3R Hars Figure 1 Use the Debye theory to explain the behavior of C Show that at low temperatures, C. varies as T³ (20 marks)
