Estimate the heat capacities of metals using a model based on degrees of freedom. In the chapter on temperature and heat, we defined the specific heat capacity with the equation Q = mcΔT Q = m c Δ T, or c = (1/m)Q/ΔT c = ( 1 / m) Q / Δ T. However, the properties of an ideal gas depend directly on the number of moles in a sample, so here we ...
