For many substances, the variation with temperature of the molar heat capacity at constant pressure of is given by the expression: Cp.m = a + bT + C/T² For copper, a = 22.64 J K-1 mol-1, b = 6.28 x 10-3 J K-2 mol-1 with the value of 'c' being negligible. Calculate the change in the molar enthalpy of copper when it is heated from 293 to 323 K.
