Q1 The Boltzmann formula is S=klnW. A perfect crystal has a molar entropy of 0 at absolute zero because (A)W=0. (B)W=1. (C)W=NA. (D)k=1. ans:(B) 為什麼呢? Q2Which provides the greatest increase in entropy? (A) H2O (s,0℃) ===> H2O (l,0℃) (B) H2O (l,0℃) ===> H2O (l,25℃) (C) H2O (g,0.1℃) ===> H2O (s,0.1℃) (D) H2O (l,100℃) ===> H2O (g,100℃) -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 211.74.220.113
