※ 引述《pachinoya (小亚)》之铭言:
: 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 为什麽啊
: 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(隔热系统),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
这一题我觉得 会减少的原因是 绝热系统防止热功的传导
但本身还是会对系统内部吸收一点能 (例如冰用保丽龙包着 但还是会慢慢退冰
并非不退冰
