For a paticle in a box of nanometer size, the energy level is quntized as deltaE =(2n+1)h^2/8ml^ Use this information to quantitatively explain the following observations. (b)Heavy particles have larger entropy than lighter paticles of the same size of box at the same temperature. 哪個高手拜託了!! -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 114.42.103.194

(a)E(n)=n^2*h^2/8ml^2

deltaE=E(n+1)-E(n)=[(n+1)^2-n^2]h^2/8ml^2=正解

若要寫更完整則需推倒薛丁格方程式解出E(n)

普物有,普化只要記起來就可以了,化學要到大2物化才有

教推導,但台大喜歡考超出大一範圍的東西0.0

@_@ 怪不得有幾題總是得翻一翻學長課本才知道!
