This question follows the entire chain of reasoning involved in determining the specific heat of an Einstein solid. Start with two metal blocks, one consisting of one mole of aluminum (27 g) and the other of one mole of lead (207 g), both initially at a temperature very near absolute zero (0 K). From measurements of Young's modulus one finds that the effective stiffness of the interatomic bond modeled as a spring is 16 N/m for aluminum and 5 N/m for lead. Is the number of quantized oscillators in the aluminum block greater, smaller, or the same as the number in the lead block?
