A system containing four neon atoms is confined to a one-dimensional box. The system undergoes an expansion from 905 pm to 1810 pm at a fixed total energy of 14.0 x 10^-24 J. 

(a) Determine the number of microstates for both the initial and final states of the system by illustrating, in the manner of Figure 13-1, the various possibilities for distributing the atoms among the particle-in-a-box energy levels. Use a different color for each atom. 

(b) Calculate the entropy change for the system.
