Question: Determine the coefficient of thermal expansion (in m/m.K)

The potential energy between two atoms can be represented as follows: V = A B + r p10 Where A and B are constants and r the interatomic separation distance. Plot the potential energy verses distance relationships for these atoms when A= 5 x 10-30 J.m and B= 8 x 10-121 J.m10. Determine the coefficient of thermal expansion (in m/m.K) for the material over the following temperature ranges: a) O°K to 0°C, b) 0°C to 820°C. Assume that thermal energy of the system is 3kT/2 where k is Boltzman's constant k = 1.381 x10-23 J/K. Important: Submit a plot of the potential energy verses distance relationship including any markings necessary to understand how you determined the coefficient of thermal expansion.
