Figure 7.49 is a potential energy curve for the interaction of two neutral atoms. The two-atom system is in a vibrational state indicated by the green horizontal line. (a) At r=r1, what are the approximate values of the kinetic energy K, the potential energy U, and the quantity K U ? (b) What minimum energy must be supplied to cause these two atoms to separate? (c) In some cases, when r is large, the interatomic potential energy can be expressed approximately as U=-a / r^6 . For large r, what is

For a certain metal the stiffness of the interatomic bond and the mass of one atom are such that the spacing of the quantum oscillator energy levels is 1.5 × 10^-23J. A nanoparticle of this metal consisting of 10 atoms has a total thermal energy of 18 × 10^-23 J. (a) What is the entropy of this nanoparticle? (b) The temperature of the nanoparticle is 87 K. Next we add 18 × 10^-23J to the nanoparticle. By how much does the entropy increase?
