(c) Derive this increase of entropy with statistical mechanics (using the
       Boltzmann's entropy equation S = k ln W, where k is the Boltzmann's
       constant, W the multiplicity of the configuration). (10%)
   (You can use the Stirling's Approximation: ln N! = N ln N - N .)

這是怎樣阿
到底要導到怎樣的地步阿?
題目相當攏統
也不說有幾個箱子~~>"<
