[趣事] 今天學校的熱力學考題...

今天的熱力學考試 老師只放上了一張圖片 http://ppt.cc/3lGe Q: Calculate the mixing entropy of the substance(Phase B) and the entropy change of phase transformation A→B at 0K. A: (1) Smix = klnW = kln(25!/25!) = 0 Because the particles are all the same. (2) ΔS = 0 Because there is no transformation. 小魯這樣寫，不知是否正確？ --

推 Lavchi:∵ Z>B ∴ A→B has no transformation# 04/10 22:20

推 NewPoliceman:你可以把香蕉看成空位 太陽花看成原子 B有組態熵啊 04/10 22:38
