Question: a.If your graphs revealed a mathematical relationship between specific heat and atomic mass, write down an equation for the relationship. b. Comment on the usefulness
a.If your graphs revealed a mathematical relationship between specific heat and atomic mass, write down an equation for the relationship.
b. Comment on the usefulness of the determination of specific heat as a method for identifying an element. Would specific heat alone give you much confidence with regard to the identity of the element? If you think measurement of another property would be needed to support an identification, what property would you measure and why?
c. The elements listed in the table are all selected metals. The values for nitrogen, oxygen, fluorine and neon are 1.040, 0.918, 0.824 and 1.030 J/g K respectively. Do these elements fit your equation?
d. A theoretical treatment results in the conclusion that the product (Cp)(M) should equal 3R. Is this consistent with your findings?
