b) The classical Dulong - Petit Law states that Cv = 3R where R is the ideal gas capacity at constant volume. However, C, is found to vary with temperature as shown in Figure 1 at low constant and C, is the heat experimentally temperatures i. ii. Cv 3R 0 Figure 1 Use the Debye theory to explain the behavior of Cv Show that at low temperatures, C, varies as T³ (20 marks)
