Question 7 (8 points) Number of vacancies in metal is temperature dependent (a) (3 points) Calculate the fraction of atom sites that are vacant for a metal at its melting temperature of 337°C (610 K). Assume an energy for vacancy formation of 0.57 eV/atom. (b) (3 points) Repeat this calculation at room temperature (298 K). (c) (2 points) What is ratio of Ny/N(610 K) and Ny N(298 K)? (Boltzmann constant: k-1.38 10 23 J/atom-K or 8.62x10 SeV/atom-K)
