Entropy (ka/atom) 5. Consider the plot of the vibrational entropy Svib below for this material (remember 1043 K. What is the effect, if at all, = that Sko). The grey vertical line shows T of including Advib in AF = Fdis (7) Ford (7)? (2 points) 6. I guesstimated a few (T, S) points from the plot below and used my mad Excel skills to fit a logarithmic equation. After converting to 7, I got ovib = 3.6 ln(7) + 16. Derive the heat capacity of this material. Assume no thermal expansion, the thermodynamic identity is a good place to start. If it is different from the Dulong and Petit limit, why might this be?
