Re: [普化] 台大的普化考題
※ 引述《pachinoya (小亞)》之銘言：
: predict the sign of S for each of the following and explain
: (c)compressing an ideal gas at constant temperature
: 答案是S<0 為什麼啊
: how many different tripeptids can be found form one molceule each of the amin
: o acid tyrosine,valin,and alanine? 答案是6
: In an adiabatic system(隔熱系統),if work is done,the tempertature must
: (a)increase (b)decrease (c)remain the same (d)increase then decrease
: (e)decrease then increase 答案是(b)decrease
這一題我覺得 會減少的原因是 絕熱系統防止熱功的傳導
但本身還是會對系統內部吸收一點能 (例如冰用保麗龍包著 但還是會慢慢退冰
並非不退冰
