According to the Einstein model of a crystalline solid, the internal energy per mole is given by

where TE is a characteristic temperature called the Einstein temperature, and T is the temperature of the solid in kelvins. Evaluate the molar internal energy of diamond (TE = 1060 K) at 300 K and 600 K, and thereby the increase in internal energy as diamond is heated from 300 K to 600 K.
