2. (5 pts) From the figure below, find (a) (2.0pt) the heat capacities (in J/[Kmol]) of the four metals at T =298K (room temperature) and at T=100K, and (b) (3.0pt) the speeds of sound in the four metals, respectively. All of the four metals have the same crystal structure, i.e. the face-centered cubic. The lattice parameters or constants of the metals are: 0.404nm for Al,0.361nm for Cu,0.409nm for Ag, and 0.495nm for Pb. . FOR PARTS A \& B, fill in the table below (or create your own table) with your final answers.
