Problem

Silver has longitudinal and transverse sound speeds vL=3650 m s−1v_L = 3650\ \mathrm{m\,s^{-1}} and vT=1610 m s−1v_T = 1610\ \mathrm{m\,s^{-1}}, density ρ=10490 kg m−3\rho = 10490\ \mathrm{kg\,m^{-3}} and molar mass M=107.87 g mol−1M = 107.87\ \mathrm{g\,mol^{-1}}. Predict silver's Debye temperature, and compare it with the standard tabulated value, 225 K225\ \mathrm{K}.
