The specific heats of pure Ag, Cu, and Au were measured over the range 3 K < T < 30 K. Specific heat data for all three metals are tabulated and plotted. For silver the estimated values of the De-bye temperature at zero temperature Θ0 and electronic specific-heat coefficient γ are: Θ0 = 226.6 K and γ = 640.9 μJ/(K2·mol).
