Dulong-Petit rule for metals a. Consider the room temperature experimental specific heats of those 22 metals listed in the Table. They are listed in increasing atomic mass from Li to Bi. Plot cs versus 1/Mat at and find the best line that goes through the origin. What is the slope of this best line? Now consider Be, which is a very light metal. It has cs=1.825Jg1K1, Mat=9.012gmol1. What is its molar heat capacity? What is your conclusion? (To avoid points cluttering in one region of the plot, you can also try a loglog plot.)
