Ch11 HW3 (Homework) Arthur Barfield PHYS 2211, section M, Fall 2008 Instructor: Jennifer Curtis Web Assign Current Score: 25 out of 25 Due: Friday, December 5, 2008 09:00 AM EST Description Specific heat capacity of a solid Instructions Reading: Section 11.6 and previous sections. On this assignment you are allowed three submissions per question part. The due date for this assignment is past. Your work can be viewed below, but no changes can be made. 1. [MI2 11.P.56.alt02] 14/14 points 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 these oscillators is 4 times the calculated value given above. Use these precise values for the constants: = 1.0546 10 -34 J · s (Planck's constant divided by 2 ) Avogadro's number = 6.0221 10 23 molecules/mole k = 1.3807 10 -23 J/K (the Boltzmann constant) In order for WebAssign to be able to give you sensible feedback, you must give 5 figures in your answers for E and S.
