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?

SOLVED: The interatomic spring stiffness for tungsten is determined from Young's modulus measurements to be 90 N/m. The mass of one mole of tungsten is 0.185 kg. If we model a block of tungsten as a collection of atomic "oscillators" (masses on springs), what is one quantum of energy for one of these atomic oscillators? Note that since each oscillator is attached to two "springs", and each "spring" is half the length of the interatomic bond, the effective interatomic spring stiffness for one of
