5.6.1 The graph shows in blue a lattice dynamics result, and in red, a Debye model fit, to the heat capacity of lead.

A) By what factors would you change the mass and lattice constant for the lattice dynamics calculation to improve the fit?

B) By what factors would you change the velocity of sound and lattice constant for the Debye model to improve the fit?
